Things I liked: This gun is accurate, easy to shoot, and quiet enough that it won't disturb the neighbors. So far is has shot all the pellets I've tried with good accuracy, some just slightly better than others.
Things I would have changed: Double cocking the gun could result in damage. It would be nice if that wasn't a concern. If you aren't sure you cocked it it's safer to put a pellet in and pull the trigger than to double pump.
What others should know: For target shooting indoors or out this makes a fantastic first air rifle to own. The stock is easy to adjust, and you'll never have to wonder if the gun is accurate. I started with some cheaper "starter" guns and wish I'd saved my money and bought this one the first time. I put a UTG scope on top and the shooting experience is top notch.
