## Customer Reviews

### ⭐⭐⭐⭐⭐ It worked
*by J***  on February 15, 2023*

I have a hand massage gun and I had lost the power cord. Without being able to find the right brand I had to order a power cord just off of the Amazon wattage. And this worked great.

### ⭐ Wrong voltage, doesn't work
*by J***E on April 5, 2024*

This listing has pictures of the Costco massager, and that is what I purchased it for. The massager requires an 8.4 volt input, this listing says it has an 8.4 volt output, but the output on the device says 8.6 volts, and the massager will not charge. Either they screwed up or this listing is an outright lie. Totally nonfunctional for the written purpose

### ⭐⭐⭐⭐⭐ Charger
*by C***B on July 19, 2022*

Exactly what I needed when I accidentally packed my original up when sending something back to a different company!
