We purchased this trap along with the similar Eaton trap; they are almost identically built.  The plus for the Eaton is that it has a clear plastic window in the lid so that you can easily see if you've caught a mouse (although you can usually hear them first).  The Tin Cat, however, is a bit sturdier.  We caught several mice in each trap; both traps are easy to open for release and easy to clean.  BUT...the mice quickly learn how to get out as easily a they get in!  My husband made a minor adjustment to the openings, and we then caught and released several more mice who apparently could not get out.  We haven't caught one in two nights, so I'm hoping they're gone!  I recommend the Tin Cat for humanely getting the mice out of your house, garage, etc.  **I would ask both companies (Victor and Eaton) to refrain from suggesting the additional use of glue strips or drowning...that's very cruel.
