Product does a good job of cleaning your firearm and making it look brand new like you just pulled it out of the box. Will always recommend to anyone.

Smell not as strong as regular hopps. Seems to take a little longer. Don't have to worry about it staining polymer stocks. Does good job cleaning bore and chamber. Does pretty good on removing copper
