"I have had this for a couple of months now and am quite pleased with it,
There are a couple of items that could be better, battery life is only a few hundred rounds so carry a spare if you are going war gaming with this, better make it two spares.
Also the battery is a tight fit, getting all the wires tucked away can be a bit of a challenge, doable but not easy.
The trigger on mine is a bit touchy in the semi position and locks up if you are not precise in your follow through, seems fine in auto.
All in all though I am quite happy, it recoils harder than a .22 version of an AR and I feel that it makes an even better trainer for this reason.
