it is what it says. it catches mice. and it doesn't kill them. it simply traps them with sufficient air and space so that they can be transported away from your area. if they keep the price low it is worth it.

For small mice, it is just what they need and it is discreet in appearance.
It didn't need to "take out its money" but the simulation is easy and has always been 100% successful. It is good to touch a wall because it is very lightweight and closes (as a good trap should) very easily.
