Tzumi Dumbbells Dropped Weight Plates on Users, Lawsuit Claims
Over 12,000 adjustable dumbbells were sold with a defect that caused heavy weights to fall during use, causing injuries. The company’s recall is inadequate, consumers say.
Tzumi Electronics sold over 12,000 FitRx SmartBell adjustable dumbbells with a design defect that caused weight plates to dislodge and fall during use. The company received more than 60 reports of plates falling and at least seven injury reports before issuing a recall in March 2025. The lawsuit alleges Tzumi knew about the defect but continued selling the dangerous product, and that the recall remedy fails to adequately compensate consumers or guarantee the defect is permanently fixed.
This case shows how companies can knowingly sell dangerous products while consumers bear the physical and financial costs.
The Allegations: A Breakdown
| 01 | Tzumi designed and sold FitRx SmartBell XL adjustable dumbbells with a defect that caused weight plates to dislodge from the handle during use. The defect created an impact hazard that could drop weights ranging from 10 to 90 pounds onto users. | high |
| 02 | The company sold over 12,000 of these defective dumbbells nationwide starting in September 2023. Tzumi distributed the products directly and through dealers and online retail outlets including Walmart.com. | high |
| 03 | Tzumi received more than 60 reports of weight plates dislodging during use before issuing a recall. These incidents caused at least seven injuries including bruises, contusions, and abrasions. | high |
| 04 | The lawsuit alleges Tzumi knew the dumbbells had inherently defective components that were not suitable for their intended use. As the designer and manufacturer, Tzumi created the defect and knew about it. | high |
| 05 | Tzumi concealed the defective nature of the dumbbells from consumers and failed to disclose the safety hazard. The company actively marketed the dumbbells as high-quality and reliable while knowing about the dangerous defect. | high |
| 06 | When Tzumi issued a recall on March 20, 2025, the company offered only to replace the dumbbell handle and storage tray. The recall mentions no testing or assurances that these repairs will permanently solve the defect. | medium |
| 07 | Consumers who purchased the dumbbells cannot reasonably discover the defect without disassembling the product and inspecting internal components. Most dumbbell dealers would not allow such intensive inspection before purchase. | medium |
| 08 | The lawsuit alleges Tzumi knew or should have known about the defect before selling the dumbbells to consumers. The company had superior knowledge about the true state of the product but failed to warn buyers. | high |
| 01 | Tzumi sold over 12,000 defective dumbbells between September 2023 and March 2025 before any recall action was taken. This 18-month period allowed thousands of consumers to purchase and use dangerous products. | high |
| 02 | The company had a duty to ensure the dumbbells functioned properly and safely for their advertised use and were free from defects. Upon discovering a defect, manufacturers must explicitly disclose it and either correct the defect or stop selling the product. | medium |
| 03 | No pre-market safety testing appears to have caught the design defect before over 12,000 units reached consumers. The defect only became publicly known after numerous injury reports accumulated. | high |
| 04 | The recall was issued only after the Consumer Product Safety Commission became involved. The CPSC announcement on its website was the primary public notification of the hazard. | medium |
| 05 | Tzumi failed to provide adequate warnings about the defect before or at the time of sale. The company did not strengthen warnings or provide adequate safety disclosures despite knowing the risks. | high |
| 01 | Tzumi manufactured, marketed, and sold the dumbbells under the guise of them being safe and operable. The company actively promoted the products as high-quality while allegedly knowing about the dangerous defect. | high |
| 02 | The lawsuit alleges Tzumi concealed or failed to disclose the defect to induce consumers to purchase the dumbbells. The company intended for consumers to act upon the false presentation of safety as part of its commercial operations. | high |
| 03 | Consumers would not have purchased the dumbbells or would have paid less if they had known about the defect. Tzumi prioritized sales over providing accurate safety information to buyers. | high |
| 04 | Despite knowing the risks, Tzumi did not strengthen warnings or provide adequate safety disclosures before selling the products. The company actively concealed or ignored the need for stronger warnings, prioritizing sales over consumer safety. | high |
| 05 | Tzumi accepted payment for dumbbells without providing safe components. The company sold products with defective parts that present serious safety risks while accepting full price from consumers. | high |
| 06 | The recall remedy offered by Tzumi simply replaces defective components with other likely defective components without fixing the root cause of the defect. This approach minimizes cost to the company rather than fully compensating consumers. | medium |
| 01 | Consumers paid full price for dumbbells that were worthless due to the dangerous defect. They received unsafe products instead of the quality training equipment they believed they were purchasing. | high |
| 02 | The dumbbells now have diminished resale value because of the known defect and recall history. A dumbbell with a known history of a dangerous defect is worth much less than a dumbbell with a safe design. | medium |
| 03 | Consumers are in a much worse bargaining position when trying to sell their dumbbells than if Tzumi had properly manufactured, designed, produced, distributed, and advertised the products. The recall has permanently damaged the product’s value. | medium |
| 04 | Consumers have spent hours and will spend more hours dealing with the recall process. The recall amounts to time and dollars needlessly taken from consumers because of Tzumi’s actions. | medium |
| 05 | Even assuming the recall offered a true fix, consumers are still burdened with a devalued product. The value of an adjustable dumbbell with a known history of a dangerous defect is worth much less than one with a safe design. | medium |
| 06 | Tzumi was unjustly enriched by accepting money for products it knew were defective and unsafe. The company voluntarily accepted and retained benefits conferred by consumers at their expense. | high |
| 01 | The dumbbells posed a serious risk of impact injuries because weight plates weighing up to 90 pounds could suddenly drop on users during exercise. The risk of heavy plates coming loose and dropping onto users posed a serious risk of injury. | high |
| 02 | At least seven people suffered injuries from the defect including bruises, contusions, and abrasions. These documented injuries prove the defect caused actual physical harm to consumers. | high |
| 03 | More than 60 incidents of weight plates dislodging during use were reported. Each incident represented a potential for serious injury depending on the height from which plates fell and where they struck the user. | high |
| 04 | Over 12,000 consumers purchased and potentially used these dangerous dumbbells. Each unit sold represented an ongoing hazard in someone’s home where it could injure the owner, family members, or others. | high |
| 05 | The defect made the dumbbells unreasonably dangerous and not reasonably fit, suitable, or safe for their intended purpose. The risk of injury far outweighed any benefits of the product. | high |
| 06 | Consumers had no way of knowing about the latent defect. An ordinary consumer would not expect a dumbbell to have weights that dislodged and fell off during normal use. | medium |
| 07 | The weight securing mechanism is one of the most critical aspects of an adjustable dumbbell’s safety. The fact that this essential safety feature was defective made the entire product dangerous. | high |
| 01 | Tzumi failed to stand by its warranty obligations. When a manufacturer provides a warranty, it must stand by that warranty, but Tzumi failed to do so. | medium |
| 02 | The company failed to explicitly disclose the defect after discovering it. Manufacturers have a duty to disclose defects and either correct them or cease selling the product, but Tzumi continued sales. | high |
| 03 | Tzumi had access to critical safety information regarding injury hazards but failed to warn consumers. The company left buyers unaware of dangers while possessing knowledge that could have prevented injuries. | high |
| 04 | The company had access to industry knowledge, safety reports, and consumer complaints that should have alerted them to the defective nature of the products. Despite this knowledge, Tzumi continued selling the dangerous dumbbells. | high |
| 05 | Tzumi could have implemented safer design modifications that would have reduced or eliminated the injury risk, such as better securing the plates. The company had the ability to manufacture a safer product but failed to do so. | high |
| 06 | Alternative, safer dumbbell designs were available that did not have weights that dislodged and fell onto users. Tzumi chose not to use these safer designs. | medium |
| 01 | Tzumi marketed the dumbbells through active and persistent promotions touting their quality. The company built its reputation through marketing that emphasized the products as high-quality and reliable. | medium |
| 02 | Consumers like the plaintiff decided to purchase based on Tzumi’s reputation gained through marketing and promotion. The plaintiff believed the dumbbells were high-quality, highly reliable, and came with great technological features. | medium |
| 03 | The recall offered to repair and replace faulty parts but provided no assurances of comprehensive testing. The company mentions installing a new dumbbell handle and storage tray but provides no testing guarantees. | medium |
| 04 | Tzumi’s recall does not offer any reasonably foreseeable guarantee that the defect will be permanently eliminated. The remedy appears designed to address immediate safety concerns with minimal disruption to the company. | high |
| 05 | The recall focuses on mitigating further direct physical harm and limiting legal exposure rather than rectifying all aspects of consumer loss. The approach does the minimum required rather than making consumers whole. | medium |
| 01 | This case arises from Tzumi’s breach of its duties and rules regarding product safety. Training equipment manufacturers must follow basic rules and procedures to ensure products function properly and safely. | high |
| 02 | The situation represents a fundamental breach of trust between a company and its customers. Consumers relied on Tzumi’s marketing and quality claims only to receive dangerous products. | high |
| 03 | The lawsuit seeks to remedy various violations of law in connection with Tzumi’s manufacturing, marketing, advertising, selling, warranting, and servicing of the dumbbells. Multiple aspects of the company’s conduct are challenged. | medium |
| 04 | Consumers purchased products at a premium price based on representations that the products were fit for ordinary use when they were not. The deceptive acts injured consumers who paid full price for defective goods. | high |
| 05 | Even if Tzumi’s recall were effective, consumers would still be burdened with devalued products. The recall does not address the permanent damage to the products’ reputation and resale value. | medium |

Direct Quotes from the Legal Record
“Training equipment manufacturers must follow certain basic rules and procedures. When such a manufacturer sells a training product, it has a duty to ensure that the product functions properly and safely for its advertised use and is free from defects. Upon discovering a defect, a manufacturer must explicitly disclose the defect and either correct the defect or cease selling the product. When a manufacturer provides a warranty, it must stand by that warranty.”
💡 This establishes the fundamental duties Tzumi allegedly violated by continuing to sell defective dumbbells.
“Specifically, the Class Dumbbells’ Weight plates can dislodge from the dumbbell handle during use, posing an impact hazard to consumers.”
💡 This describes exactly what went wrong with the dumbbells and why they were dangerous.
“To date, there have been more than 60 reports of weight plates dislodging during use, which have been linked to at least seven injuries, including bruises, contusions and abrasions.”
💡 This proves the defect caused actual harm to multiple consumers, not just theoretical risk.
“Defendant’s Recall, which includes a free fix-and-repair clause requiring Defendant to repair and replace the faulty parts, does not offer any reasonably foreseeable guarantee that the Dumbbell Defect will go away permanently. Rather, the Recall mentions installing a new dumbbell handle and storage tray, but mentions no testing or assurances that such repairs will solve the issue fully.”
💡 This shows Tzumi’s recall may not actually fix the problem or compensate consumers for their losses.
“Assuming that the Recall was effective and offered a true fix, which it does not, Plaintiff is still burdened with an adjustable dumbbell that has been devalued by Defendant’s actions, because the value of an adjustable dumbbell with a known history of a dangerous Defect is worth much less than a dumbbell with a safe design.”
💡 Even a successful repair cannot restore the financial loss consumers suffered from owning recalled products.
“Defendant knew that the Class Dumbbells suffered from inherently defective components that were defectively designed and/or manufactured and were not suitable for their intended use. Defendant designed, engineered, and produced the Class Dumbbells; therefore, it created its own Dumbbell Defect and knew of that Defect.”
💡 This alleges Tzumi was not surprised by the defect but created and knew about it from the start.
“Defendant concealed from and failed to disclose to Plaintiff and Class Members the defective nature of the Class Dumbbells.”
💡 Tzumi allegedly hid the defect rather than warning consumers, prioritizing sales over safety.
“The fact that Defendant’s Class Dumbbells contained the Dumbbell Defect is a material fact, because a weight securing mechanism is one of the most critical aspects of an adjustable Dumbbell’s safety.”
💡 The defect affected the most essential safety feature, not a minor cosmetic issue.
“Plaintiff and Class Members would not have purchased the Class Dumbbells had they known of the Dumbbell Defect. Plaintiff and the Class did not know of such Dumbbell Defect; in purchasing Class Dumbbells, they relied upon Defendant’s false presentation of safety.”
💡 Consumers made purchasing decisions based on false information about product safety.
“Plaintiff did not know of and could not have discovered the Dumbbell Defect unless Plaintiff were to disassemble the Class Dumbbell and inspect the components throughout the Class Dumbbells. This possibility exists outside of reality, because—even if such a possibility would occur to an ordinary consumer—it is highly improbable that any Class Dumbbell dealer would allow for such intensive inspection.”
💡 The defect was impossible for consumers to detect before purchase, giving Tzumi an information advantage.
“Defendant was under a duty to Plaintiff and Class Members to disclose the defective nature of the Class Dumbbells because: Defendant was in a superior position to know the true state of facts about the Dumbbell Defect contained in the Class Dumbbells; The omitted facts were material because they directly impact the safety of the Class Dumbbells; Defendant knew the omitted facts regarding the defect were not known to or reasonably discoverable by Plaintiff and Class Members; Defendant actively concealed the defective nature of the Class Dumbbells from Plaintiff and Class Members.”
💡 This establishes multiple reasons why Tzumi had a legal obligation to warn consumers.
“Defendant concealed, or failed to disclose, the true nature of the design and/or manufacturing defects contained in the Class Dumbbells, in order to induce Plaintiff and Class Members to act thereon.”
💡 The concealment was intentional to drive sales, not an innocent oversight.
“There were alternative, safer Dumbbell designs available that did not pose similar injury risks, meaning Defendant could have implemented a safer design but failed to do so.”
💡 Tzumi chose not to use known safer designs, showing the defect was avoidable.
“Defendant’s acts were and are materially misleading because Defendant in fact sold the Dumbbells into commerce which were defective and posed a risk of dislodging heavy weights that could fall on users, causing injury. Plaintiff and the Class have been injured because of Defendant’s deceptive or unfair acts, because they purchased Defendant’s Products at a premium price on the basis of the fact that those Products were fit for ordinary use when they were not.”
💡 This explains how Tzumi violated state consumer protection laws through deceptive practices.
“Because this benefit was obtained unlawfully—namely, by selling and accepting compensation for the Class Dumbbells without providing safe components in the Class Dumbbells—it would be unjust and inequitable for Defendant to retain the benefit without paying the value thereof.”
💡 Tzumi profited from selling defective products and should not be allowed to keep that money.
