From the performance, looks, and build quality, to the adjustable outer diameters, this hop up unit is the clear winner. After cracking the original cheap overpriced plastic one, I decided I’d rather take a dremel the gearbox shell before buying another one, and I’m glad I did. After some “light” modifications, fitted to a Krytac Kriss Vector

Replaced my ProWin for the MAXX ME-PRO, improved both air seal and groupings. Running on ORGA barrel, Prometheus Purple hop bucking, Firefly Namazu Flat hop nub and the Maxx-ME PRO.

At first I just figured this was gonna be another all show pretty hop up ...... but boy was I wrong. This thing must be forged in the heart of a Star by unicorns and magic elves because it makes a gun run so much more efficiently, and accurately. Just by swapping to this hop up with the maple leaf bucking, I saw a .08j increase in my guns output with no other changes (around 5-10 FPS) so I would highly recommend it

The ME pro is more forgiving then the older TE version. Fits and feeds perfectly in my gun.

The hop unit is well worth the money and comes with some great parts like metal nubs for flat hop and it’s just crazy how much is adjustable with parts to work in varying setups. Would recommend and will buy again for other builds
