I bought this because I liked the way it looked over the Rocket Cock. Also, at the time, the only Rocket Cocks were plastic - and I made it my mission to get rid of as much plastic as I could on my marker. It blocks paint from getting in you rear bolt and theres nothing to move and hit your mask. However, you still have the rear part of the T handle sticking out farther back than the original cocking nob ever went. So, if you were hitting yourself in the mask or something with your stock cocking knob, you're not going to be able to get your gun that close to your face anyway. That's not really a big deal. I'd say the main reason to get this would be to not get pain inside the rear bolt.
Problems I've had with it, were that the little rubber stopper you put in is not quite large enough in diameter to keep the T handle from falling back. So when you're running hard sometimes it will slip back and forth making noise, and generally once it falls out, you have to push it back past the rubber stopper to get it to go in, so if you sprint somewhere, then are trying to hide behind some brush, if you forget to put the T handle back in, it will rattle at times when you'd rather not be making "clank clank".
The handle does not return by itself. I modded mine to make it automatically snap back in to position using an elastic. I believe I'm the first to do this =) You should be able to figure it out yourself, but I'll be posting on PBnation soon with some pictures.
A bit expensive I think, they're making a killing, but it works.
