"Got this for my G&G ARP-556 2.0 and it worked great!

Easy to install with amazing features. Highly recommend.

"Great mosfet. Used to replace old g&g mosfet on my G&G CM16 SRL. Fixed problems immediately. Now I can use my deans batteries, fit bigger batteries, and have more options when it comes to programming. Programming instructions included in the package are extremely helpful and easy to follow. I can program binary, burst modes, and it even tells you what is wrong with your gun if it is not firing. One of the best $50 bucks you can spend to upgrade your G&G gun.

"I bought this because I've had two original g&g mosfets fall apart on me, and it was very difficult to find batteries that would fit properly and allow full adjustability of the stock. This Perun is easy to install, smaller, better built, and far more flexible than the original mosfet that my gun had (G&G Knights Armament SR30). It increased my rof a little bit, and due to it's flexibility, I have more battery options. I highly recommend this if you're experiencing hiccups with your current g&g mosfet.

"This unit is amazing. I had an original ETU+ in my ARP9 DSG build that was giving me issues. It turned out to be the wiring had been damaged, but I couldn't figure it out. Fast forward to this puppy coming out; it tells you what's wrong with its LEDs during start up!

Thanks to its diagnostic properties, I was back up and playing quickly after installing this MOSFET. I cannot recommend Perun enough. Any time I have issues, Jakub from Perun is quick to respond to emails and is extremely helpful. They really do care about their customers.

This unit does nothing wrong and everything right. It's easily programmable on the field to change up your playstyle. It helps you when teching goes wrong. I installed one of these into an RK-74e that had terrible spring noises on each shot and with stock settings the sound was cleared up - I didn't even have to remove the gearbox from the replica! It can handle high ROF and high FPS builds with ease. If you're building 50+ RPS guns though, you may want to look elsewhere, as the 'FET does only guarantee compatibility with 50 or less RPS replicas.

If you have a G&G gun with the ETU and you like the triggerpull and the overall feel of the system but want it to be a little snappier/faster/precocked/better, GET THIS UNIT!
