Things I liked: Seems pretty accurate. Definitely a good value, since it isn't particularly expensive.
Things I would have changed: A redesign of the rear end would be nice so that it would be easier to load. Also, changing the rear end somehow to make it easier to cock without pushing on the rear sights would be nice. I guess that's just one of the problems with this type of gun, but there's got to be a better way to set that up.
What others should know: A little difficult to load. Easier if you have small fingers. Every time I go to shoot it after not shooting for a little while, the first time I cock it it doesn't charge with air. Don't know why. But now I just cock and dry fire it, then start shooting. First time it happened I thought I'd gotten a lemon. All shots after the first are just fine though. I don't have a chrony, but the sound it makes on my target says it's hitting about as hard as it should be. Definitely not really powerful enough for pest control. It isn't advertised as being powerful enough for this, I don't dock it for this, but if anyone thinks it is, it isn't.
