Ive heard people rave about them. Also heard people say they had issues, and that they were coming out with a new revision to address the issues. As far as I know, the new revision is not out yet, but I dont follow them too closely to be 100%.
To me, I would rather buy Magpuls for the same price. I have also been running Lancers when I can grab them on sale. I really like the smoke and translucent FDE Lancer's.
