Yep, can certainly recommend (assuming this one represents the standard)
I think its stock right @Shamal?
The blowback effect is minimal but better than not having it.
Nice and snappy on 7.4v LiPo. 1300mAh almost lasted the full day. (It died in the last game. Next time I'll change at lunch)
The MOSFET (proprietary I think) works really well so lockups experienced. (Only used semi)
The selector can be a bit fiddly. With 4 modes its easy to get knocked into a different one. (I did fire a few on burst when I thought it was semi)
