Great Product, good when you need to open the motor again
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
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
Haven't used it yet but it had a sticker covering up a label that said for sale in India only.
