I am using it right now while I'm writing this blog in my CR-48. Actually, it just hard to type with this thing on. It suppose to be a slide bands for your fingers while your surfing in the web while using Chrome browser, you actually don't need to use chrome but I feel sorry for you if your actually not. The bands actually looks cool but personally its just a gimmick. I'd keep this just as a souvenir from Google, I'm sure it's all over eBay by now at the time of this writing. And I can't believe people are buying. Like I said, good as a souvenir.
When you wear them, they do feel warm after a couple of minutes, now I can see this when I'm in the office and the AC is blowing like Antarctica. I applaud Google for little stuff like this, a lot of people I'm sure are bit happy today for small things like this that they find in the mail. I am happy for this, although I'm still not sure where to use them. I'll post picture soon.
