The Good: light, strong
The Bad: has some proprietary parts
I had this set on a bike that I sold a year ago and liked the wheelset so much that I got the newest version (white with black graphics). They are essentially the same wheels minus a few cosmetic tweaks.
If you are a tubeless rider take a close look at these wheels. You can run a tubeless set-up without fussing with funky conversion kits or adding extra weight to your wheels. They look great too and work on everything from AM to FR to all but the craziest DH, where you might want wider and heavier rims. However, I did see a few riders running these at the Rampage and so I can't imagine a better endorsement. I just wish the rim were a little wider to give bigger tires a better profile.
The only reason to shy away is if you absolutely hate proprietary parts.
