Review title: Bad dongle, had to return 2 weeks later for replacement
Product review: When it works, this is a great keyboard with the built in trackball, but the first one I received quit working after a couple weeks. Tried everything, would link up for a few seconds then loose the connection. Ended up contacting Adesso and they said the usb dongle was bad. Returned to Amazon for a replacment, so far so good (knock on wood).
