i love this tank, the on/off is so easy to use. I love the drop forward on this thing. its just right for me. a lot of people say oh its too small it needs a bigger one to make my gun more compact. well from my experience and maybe someone you heard of, rocky cagnoni says frontplayers should just put there tanks right to the back of there gun because dropforwards bring the tank down and forward making your gun taller. anyways, the tank performs great on my tippmann so i cant imagine how good it will work on my next gun, (titanium matrix lcd),.
i really haven't found anything bad with this system, to take the tank off the gun might be a little annoying, but if you get round tipped allen keys it makes it a lot easier to take off.
i think this is a great tank really worth the money and you dont have to spend extra on a drop forward because the tank already comes with one.
