I have the White and find it pretty comfortable-- though I would personally prefer a metal band, I think, as that's what I'm used to. It's also impressively stain-resistant; I spilled curry powder on it when making dinner the other night, and fully expected a disaster as that stuff will stain nearly anything. It brushed off with no trace whatsoever, which really impressed me!
Word of warning: don't wear it too tight. I did, and got a rash from it. Once I started wearing it on the next hole all problems went away, though. I think water was getting underneath it when I was washing my hands, and the band was so tight it could not quickly evaporate? Either way, wearing it one hole looser has made an impact on the condition of my skin without any noticeable effect on HR monitoring or unwanted locking, so don't be worried about having it move around a little.
