I just won one at OP greylings I won't receive it until the middle of June but I've done some research a great review on it is done by bingo airsoft. Tbh though for the price the SMP would be better its simpler more efficient and easy to install. The quality is better than the V12 as well and you don't have to sit there for 10 mins programming it.
