It worked fine for a few week then it started only working sometimes. Not the best sound quality either.

Well, it was working great for a few weeks - nice fast speeds through my USB 3.0 port, when suddenly it stopped working.  Fiddling around with it, it appears that the USB3 "in" port connecting to the computer is loose and the cable needs to be in a specific position to connect.  Considering that I velcro-ed it into place when I first got the thing and I haven't been moving the cables in and out, it would seem that just the light weight of the cable was enough to loosen the solder points or connector.  Very poor workmanship.

It worked for just a few times over a week. After each usage, it was rinsed properly. Yet, after a week, I could no longer turn it back on. Changing into new battery is not helping!

This item installed properly under Windows 7, but died after 2 weeks of occasional use. I installed the drivers that came w/the product and everything worked fine for a few days. Then I noticed it was powered off and unplugged it and plugged it back in. After that, it would drop in the middle of a game (bluetooth headset) and randomly disappear from available devices. I've tried it in multiple computers, to no avail. Avoid.

I loved it for a couple of weeks and now it works intermittently.  I have to pull it out and give it a whack and then it might work.
