"Works great, its very very touchy though. (Barely move it to adjust alot) I recommend this to anyone who is trying to lift bb weight .28's and higher only. Works best with those weights from what I tested.

"this is a very good hop up unit. it solves all of the problems of a traditional hop up so if your gun cant fit prowins or other aftermarket units this is perfect. for the price its great and i recommend it to anyone who is looking for a budget hopup unit.

"I just recieved this today and very amazing hop up. I was able to put it together in under 9 mins. And i was reading other reviews and i read that it will not fit into g&g guns without modification to the wings but i was able to slide it in without a problem. I have a g&g cm16 raider.

"Great hop-up for the price! Fitted into my APS Guardian with no modification required. Replaced the Sh*tty APS hopup (which don't actually hop) and along side of a Maple Leaf 75degree bucking increased my fps by 60-70.

"I run this with a mad bull black python 363, prommy soft bucking, with a madbull H nub. By far the best setup for range and accuracy. Versital: works great for both AEG and P*. Only draw back was that I had to add an extra o-ring to the adjustment wheel to lock it in place. Personally I prefer this hop up over the pro win.

"Purchased this unit about a week ago, it preforms beautifully. It may require some sanding on the fins to fit smoothly into your gun, but it is an extremely solid and powerful hopup unit. Very sturdy build quality and great preformance.

"I purchased this for my G&G raider combat machine (short) It came in fast, and the product was solid and very tight when I put it together. It just didn't perform in my gun. The bbs wasn't firing well out of my barrel.

Pros; the hop up is well built, and very tight fitting in my gun to seal off air and whatever else, it just didn't work in my gun. I would recommend this product for sure. just not for a Combat machine.

"This hop up has very good wheel adjustment and gears that make it easy to adjust in very small encrements. The draw back to this unit is it dose not fit in g&p guns with out modification. Good hopup but could be better if the little wings on the sides were thinner it would fit w/o mod.
