"Works fine, and only needed replacing because i accidentally reversed the battery polarity and it fried the circuit board immediately.

It would be 5 stars, but for something this complex and expensive, there is no excuse to not incorporate reverse polarity protection, especially when it is popular to change the stock connectors on airsoft guns.

"thumbs up 5/5 really good. only con is, its not compatible with all my other guns ONLY a replacement for the ares gearbox efcs. when i first got, it was fine then it went hay wire and only did 5, 6 round bursts before dying, but i worked out the gear sensor was a tiny bit off so i pressed it in and it was all good. second con, you have to spend 60 bucks for the programmer.
