One of my friends has one. Besides a broken oring in the ram and worn detents when he got it the thing shoots ropes. Very light and small gun and the trigger is great when it's setup right. nice little gun.
One con is the eye piece. It is a single part, that covers the front of the marker, and both eyes. Tehe problem is that it is hard, and can break easily when taking them off. (I broke them ;0 ) The good news though is you can buy new 3 piece eye covers for $12.
But yea, it is compact, little kick, pretty good efficiency and it comes with a barrel kit.
