    "I love the idea of a micro switch MOSFET trigger unit at a low price, but it seemed too good to be true—until I saw this and couldn’t believe it until I got it. It literally didn’t work at first because it was too close to the sector gear, but now it works great. Still, I’d recommend saving a bit more for a Perun or a Gate Aster/Titan, or if you’re on a budget, go for an EShooter Kestrel, which is the same price but uses a switch instead of a light sensor, making it less finicky.

    pros
    cheep
    improvs trigger response Hella lot
    comes stock w deans connector
    speed trigger compatible

    cons
    super finicky
    if you get grease on the sensor d4/d5 it will not work
    so over all a pain to get working but cheaper then other if you got time to tech it

    so over all 4/5

    "This is a combined review of the mechanical V2 and V3. The V3s are great, absolutely no issues. However, every single V2 unit I had failed. It would not fire and the red light would blink rapidly. Otherwise I am very happy with its performance the V3 ones I have are still going strong. Have installed them in CYMA AKM and AKS74U, Echo1 RPK and ICS SG552. Yes although it is wired for an Ak top dust cover, you can add length to make it front or rear wired. Make sure you place the sticker underneath the board to prevent short circuit. For the gel blaster cables I just twisted them off since they are pretty thin, otherwise you can clip them. By far precocking is my favorite feature. For the price you cant really beat it. The Eshooter etu is an equivalent that I will also review later.

    "I like the price and it worked well with an 11.1V. I did have to do a little filing to mount it and rout the wires but nothing crazy. Programming was easy, but my biggest complaint was that the pre-cocking feature seems to do nothing at all. everything else was good.
