Jawbone Up great (when working) (which it doesn't)

Heed this warning if you are considering buying a physical activity tracker of some sort.

1. I have the Jawbone Up 2nd Generation. And I think it's pretty awesome.
2. It's only awesome when it works.
3. It doesn't work a lot. I've had mine for less than six months and it is inoperable for the second time. The first time they sent me a replacement fairly quickly. That replacement worked for a while and now it is not working again. I'm trying to get a replacement (for the third time).

It's a great product when it works. I'm just not sure I would buy this one if I had it to do over again. Mostly this is because it doesn't stay working. And if you check the Internet, many people have these and theirs has issues as well.

You've been warned.

Edit: I'm communicating with Jawbone support. Hopefully they'll send me another one soon.
