"This thing is a piece of trash, I have gone through 3 of these things and all of them have either burnt out or had a system failure.

The first one I received, I installed perfectly. I had to sand down my gearbox a little but other than that it fix fine. But then I plug in my battery and it fired once and a tiny piece broke off.

The second I had my friend install who is a pretty good tech. He even upgraded the gearbox, new shims, shs gears, new piston, nothing in my gun was stock. I go outside to shoot it because it was good to go, and I went through about 375 rounds then it had a melt down and started shooting full auto.

The third and final one I stupidly purchased was installed by my other friend who is a mediocre tech, got it in, didn't even shoot. It just started to smoke, I was using a 9.6v battery, HOW DOES THAT EVEN HAPPEN M8. THIS THING IS DESIGNED TO TAKE 11.1 LIPOS AND IT SHORTS OUT ON A 9.6.

Never, ever, ever, ever, EVER buy this thing. It is a waste of good money. Buy a g&g ETU or the one made by ameoba because if they break it's only 50 bucks you spent and not a 100 wasted. Maybe if you have the money, just buy a BTC cuz they good as hell man. My friend has one and it is SOOOOOO sick with the ASG 28 tpa motor. Definitely buy that it is worth every penny, and not the ASCU.

"After having a terrible experience with Gen1 and Gen2, I figured I would give this new Gen4 a try.

I just got it in the mail today. The installation was not great. The fit was VERY tight. After a little sanding on the large plastic cover, I got it to fit snug. I wired it all up being careful not to strip or pinch anything, plugged a 7.4 in and it fired fine three times. Then I could smell smoke and it started firing on auto by itself.

I took it out and observed that one of the mosfet had burned. Save yourself the $100 and find something else.

This is probably the worst airsoft investment I've ever had.

"My personal experience with this product was rather poor. The connectors between the two control boards broke quite soon, so I'm afraid I can't recommend this product. It's extremely poorly designed, for the price, there are many better options.

Pros of any simple mosfet system:
-Protects your trigger contacts and electrical system

Pros over simple mosfet systems:
-Marginally reduces trigger pull force
-Ensures a full piston cycle (improves trigger response and mechanical longevity)
-Three round burst if you want it
-No soldering required

Cons:
-EXTREMELY fragile connectors are prone to breaking at the slightest touch
-Uses extremely stiff wire instead of wet noodle wire, making the install a pain
-Poor electrical design, many users say it burns itself out extremely soon

Really, the only core advantage of this mosfet over cheaper and simpler systems is that it gives you full piston cycles. The reduction in trigger pull isn't very perceptible, three round burst is really just a gimmick, and any good airsoft tech should be comfortable soldering.

Furthermore, the warranty service is seemingly nonexistent, as I have emailed them twice about my problems to no avail.

So, I'd advise you to stay away from this product. If you want a mosfet that gives you full piston cycles, I'd recommend one of the mosfets made by Black Talon (not offered on Evike.com). They have superior construction, better warranty, and are simply a better product for almost the same price. They might 10 or 20 dollars more than the ASCU, but it's well worth it.

If full piston cycle isn't important to you, then learn to solder and make your own darn mosfet. It quite literally costs 10 dollars to make one.

The point is, stay away from this POS.
