The two I've owned were essentially worthless. The first patterned so badly I was convinced there was something wrong with it. I got rid of it and bought another that patterned even worse, if that was possible. By 'bad' I mean 3' at 7 yards worth of bad.
The other down side is the horrendous noise from that pathetic barrel. I'll guarantee you, you'll never shoot it a second time without ear protection! Save your money. I'd sooner carry a sharp stick or a pocket full of rocks.
