Things I liked: So far it stands up well to 400 fps .177.
Things I would have changed: Paint it white (I did), I could not see the sights on my gun (iron) against a black background. I then painted the hangers white and the targets black. It's now almost perfect for me.
What others should know: I used a 1x2 across the bottom to mount it to an old camera tripod. It's fast to set up now.
Things I liked: For the money this is a really great bargain. I chrono'd Meisterkugln 8.2 at 355-355-358-354-356. Those pellets shoot a ragged hole at 25'. RWS Hobby (as a practice pellet) worked well, too. Really decent trigger, easy to adjust to 2 lb. and it holds the setting well.
Things I would have changed: If there was a way to smooth out the operation of the bolt it would make this almost perfect.
What others should know: The plastic grips are hollow and cannot be modified,
