## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Product, good when you need to open the motor again
*by A***R on July 15, 2025*

Did a good job. My motor was making a rattling sound. This kept the bearing in place and the motor is now smooth like new.

### ⭐⭐⭐⭐ Maybe not what I needed
*by R***P on June 21, 2024*

Bought this to retain pin in a revolver which was walking out when shooting. Didn't want to stake the pin. This didn't work even after 2 attempts and cleaning prep. Ended up using clear finger nail polish

### ⭐⭐⭐ Not sure what to expect
*by I***  on November 12, 2024*

Haven't used it yet but it had a sticker covering up a label that said for sale in India only.
