Things I liked: Fun to shoot; safer to shoot than BB or pellet guns; inexpensive; can carry in pocket; comfortable grip; easy to cock; short trigger pull; quiet.
Things I would have changed: Better accuracy, but that's probably not possible with such a short barrel and lightweight ammo. Shoot at bigger targets and you'll have just as much fun.
What others should know: The ammo that came with my gun is .12 g. weight which is way too light - they rise 3-5 feet over a 50 ft. distance. I tried .25 g. but they are too heavy - they shoot low and to the right. The .20 g. ammo is the best fit. I'm using the bio-degradable type, so I can't comment on the accuracy of regular ammo.
