Things I liked:Price, power Things I would have changed:Better quality What others should know:I bought this gun in 22 cal because I wanted a high powered air pistol at reasonable cost. I was very disappointed in the quality: within the first 100 rounds the elevation adjustment screw popped out of the rear sight into my lawn, never to be seen again. After I fixed that, within another 100 rounds the gun literally came apart while I was cocking it. The barrel and power plant separated from the grip and could not be reassembled. Umarex was VERY helpful and replaced the gun with an RWS Diana LP8 at a substantial discount, which shoots beautifully. My advice: save your pennies and get the Diana. Only disadvantage is it comes in 177 only.
