Things I liked:What can I say, I gave it to my 14 year old daughter and she thinks it's great. As long as it knocks down cans and plastic bottles she's happy. Things I would have changed:Brand new; remove the blowback, it causes loss of velocity and the pellets get loose inside the plastic magazine, so much so that they may sometimes fall right out when it's removed. I bought 4 types of Gamo Ammo; Magnum, Master Point, Hunter, and Match and didn't notice much difference. The fps 450, If Gamo could prove that to me I'd be happy to trade the gun I have for the one they use. I'd be very surprised if it was 350 fps. Maybe they could remove the blow back and lenghten the barrel to increase fps and accuracy. Also the magazine release could have a stronger spring. If you happen to just touch it accidently the magazine pops out. But hey, my daughter doesn't mind that either as long as it pops right back in. What others should know:I would not recommend it for an adult to use as target practice beyond 20 or 25 ft.
