The RodentStop paste came as expected and appears to be everything that the advertisement states (one can see the metal flakes in the paste). It seems to do the trick of effectively filling in small exterior gaps in our house. I used the paste two weeks ago and we have not had any mice (nor have I heard any scurrying mice in the usual places) since that time. I also don't see any evidence of mice attempting to disturb those areas. RodentStop is relatively easy to use, even for someone like me who is not an efficient "DIYer". I would definitely recommend this product.
