Well, I went ahead and got the black Tread. Honestly though, I got it more as jewelry than for practical reasons. I haven't worn a bracelet in decades and this seemed like a good excuse to have one. If I ever get embarrassed by my vanity I can always say that it's "functional."
For anyone who's curious, I've attached a couple of pics. I had to remove one of the links because I have such dainty wrists. So far no issues with hairs getting pulled out. The one criticism I have is the latch is flush with the links, which is good, but so much so that it's hard to find just by touch.
It only weighs about 6 ounces but when you first put it on, it feels a lot heavier. On the plus side, you adapt to the weight very quickly - less than a day.
