As you can see, even the packaging is slightly different than the one I posted (haven't noticed it at first). There are also different specifications on the packaging, making the right one easy to recognise (* Chipset: CSR). Also, the plastic casing is a little transparent because there is a red light blinking when BT is active. The one on their page doesn't seem to have that functionality. I have no idea it that's the newer model or what...
EDIT: Did a little research and it looks like the one on their page is indeed the newer model, which is a shame, because it looks like the old one was better, but it can be still in circulation in many stores. The store I bought mine in had quite a bit of them. The photo should be a good enough reference if anybody finds one. I found many other identically shaped brands with the same chipset though, so it looks like they all came from the same factory - including some no-names and Esperansa.
The big advantage of this dongle is that it works as it should for barely $4
