I purchased this as a cheep secondary and it is over-all not too bad. It shoots around 200fps with .2 bb's. The mag is annoying to load but holds 15bbs it is very easy to pull back and it has a nice feel to pull back. The top slide is metal but sometimes you pinch your self when u pull it back. It has a under rail to put a flashlight or laser under it. It is very ergonomic and ambidextrous. The safety, trigger, and mag release are all close together and can all be used with just your trigger finger. It broke once but all i had to do was pop the slide back on and it still works the same.
Shoots decent fps
Well designed trigger (has safety, mag release, and trigger all close together)
Sometimes you pinch yourself when you pull it back
Mag is annoying to refill
