Weight is almost real. A fun marker to have, when it works.
Weaknesses:
Blow-back problems. Air flow isn't that great.
Review:
I got this for Christmas last year and it worked pretty good. I put a few clips through it, until the air flow got diverted somehow, and the blow-back wasn't too strong and you had to keep cocking it to get it to shoot. Until one day, it wouldn't even take air anymore. The blow- back wasn't that good at all in the first place. I looked at a youtube video of a guy that was shooting one, and he had the same problem. I don't really like the grip, because I am a Glock kind of person...
