I am using it everyday with communicator 2007. Overall it is a very good product. Cradle is a little too big to carry around in my laptop bag, but it comes with a USB charging cable which is fine.
My one critique is that the battery life could be better and it would help if there was a more positive off switch. Because it is difficult to know when the product is off, I have found it running flat in my bag a couple of times. Even from a good charge, I have also had it run out during important calls.
Also not sure about range. I have managed to use 3-4 meters from my laptop, but I am not sure how far I can actually get.
That said, if you can manage to keep it charged up, the call quality is great and people can't normally tell the difference vs a normal phone.
