"I really expected perfection from this unit. However inside the chamber it had a slight defect which scratches bb's and my nozzle. I spend about 2 hours carefully smoothing the casting defect away. I wouldnt expect to see that in other units, just a rare defect. This hop up unit doesn't have a notch at the top of the feed tube to prevent the bb's from slipping into the barrel from the mag pressure. Which hasn't been an issue for me but could be for others with different setups. Also the unit has material in the way where the nub touches the bucking, so if your planning on using any nubs that are longer then a standard tube nub it will snag up on it and create uneven pressure. The arm is very evenly casted and will put even pressure on the nub. The dial is very good and not super sensitive like a standard hop up. This hop up unit works better with thicker buckings, thin ones like g&g g&p lonex and such will be too thin to seal without Teflon tape.

This hop however isn't poop and is still very good and feeds very well. I'm just nit picky when it comes to spending this much money on a hop up unit, I expected better.

"I have this on my custom built P☆ HK416 and after a few tweaks. This this in deadly accurate. I play CQB indoors, I definitely think it's worth the investment. I also have other mods as well.

"This Hop Up really let me down. Having heard so much good stuff about it I decided to buy it. BBs stack up inside of it and then spors out 3-4 BBs a time. I have tried multiple barrels, buckings and nubs. The inside is too tight for the BBs to pass through.
