I love 'em! I've got them on one of my bikes, and here are some of my observations:
-great alternative to anything else out there that's mainstream. (How many different flat bars does the market need!?!?!)
-they're really cheap right now
-great hand positions (obviously)
-they seem wide at first, but in my case, I measured them and they turned out to be the same width as the previous riser bar I was using
-they may make your bike seem inbalanced (if you're into that sort of thing) unless you have some sort of rack in the back...which you may since yours is a commuter.
-they're uglier in person, and the finish gets "dirtied up" easily, which won't be a problem if you wrap them.
I posted on here before I got mine, too, so maybe you could dig up that thread. There are, I think, a few other companies that make a similar variation, which are better looking (but of course, more expensive).
