Things I liked: This is a very durable gun, as the ENTIRE body (except the grip, which is plastic but not flimsy) is made of solid metal. The whole thing comes apart with about 7 screws and one allen bolt, so if something should go wrong (my trigger got a bit screwed up once) you can easily take it apart and fix any problem due to the simple internals. There is so little to go wrong, such as not having to worry about carrying around extra mags and losing them or having to worry about the blowback system breaking (this gun doesn't have blowback). The fact that such a durable and powerful pistol is only $50, and it comes with a padded case, is just icing on the cake. The cake of CO2-induced pain.
Things I would have changed: The latches on the case are a bit flimsy, but not a big problem.
What others should know: Be careful when opening the gun, the front part tends to shoot off when you remove that allen bolt, and you might loose something important.
