October 26, 2026 — A consumer has reported a serious safety concern involving the Sharper Image Power Percussion Pro+ Hot + Cold Percussion Massager, where an attachment detached and was propelled at high speed during use, posing a significant projectile hazard.
Product Details
Incident Overview
On August 13, 2025, a consumer purchased the Sharper Image Power Percussion Pro+ Hot + Cold Percussion Massager through Instacart from Costco. The product, which includes a dual-temperature heat and cold attachment, exhibited a critical malfunction. While operating the massager at its maximum speed setting, the attachment unexpectedly detached from the device and was propelled at high speed. The incident occurred while the consumer was holding the device. Fortunately, the projectile did not strike the user or anyone nearby, thus no injury was sustained.
Upon inspection, the consumer discovered a small, almost unnoticeable defect: the attachment’s mounting point was slightly clipped and chipped. This defect is believed to be the cause of the attachment’s inability to remain secured during high-speed operation. The consumer contacted an unnamed entity and successfully received a refund, though they were unable to return the product. Costco subsequently refused a return or refund, citing that the purchase was made through Instacart rather than directly from Costco. The consumer still possesses the defective product.
Safety Concerns
This incident highlights a severe safety risk associated with the Sharper Image Power Percussion Pro+ Hot + Cold Percussion Massager.
- Immediate Dangers: The primary hazard is the detachment and propulsion of an accessory at high speed. An object ejected with force from a handheld device can cause serious impact injuries, especially if it strikes sensitive areas like the eyes, face, or head. Such an incident could lead to cuts, bruises, fractures, or even concussions.
- Who Might Be Affected: Anyone using the device, or anyone in close proximity to the user, is at risk. This includes family members, children, or pets who might be inadvertently exposed to the projectile. The device is designed for close bodily contact, increasing the danger inherent in a high-speed detachment.
- Long-Term Risks: While no injury occurred in this specific incident, repeated use of a defective unit could eventually lead to an injury. The underlying defect – a chipped mounting point – suggests a manufacturing or design flaw that could affect multiple units.
- Property Damage Potential: Beyond personal injury, a high-speed projectile could also cause damage to nearby objects, furniture, or electronic devices, though this is secondary to the human safety risk.
The fact that the defect was almost unnoticeable makes it difficult for consumers to identify the hazard before an incident occurs, elevating the risk.
What Consumers Should Do
Given the serious nature of this incident, consumers who own the Sharper Image Power Percussion Pro+ Hot + Cold Percussion Massager should take immediate action:
- Stop Use Immediately: If you own this massager, cease using it, especially with any attachments, particularly at high speeds.
- Inspect Your Product: Carefully examine the mounting points for any attachments, looking for subtle clips, chips, cracks, or other deformities that might indicate a defect. Even minor imperfections could pose a risk.
- Retain the Product: Do not discard the product, especially if you suspect it is defective. It may be needed for further investigation.
- Contact the Manufacturer/Retailer: Reach out to MERCHSOURCE LLC and Costco to report the incident and inquire about a safe resolution, return, or refund, referencing Costco item #1940218. Provide them with details of your purchase and the observed defect.
- Report the Incident: File a detailed incident report with the U.S. Consumer Product Safety Commission (CPSC) at www.saferproducts.gov. Your report helps the CPSC identify potential patterns of defects and initiate broader investigations or recalls.
