Pros: - Appears to be well built
- Has an activity LED (red)
- Very small

Cons: - The activity LED is too bright, but that can be fixed with some black tape etc.
- It's not small enough to leave in my EeePC all the time: it sticks about 1cm (1/2") out of the port
- I could only get it to work properly with the software that came with it (BlueSoleil). Without the software Windows could detect the dongle and knew what it was, but it didn't work with some devices.
But the main problem is:
- I don't know if it's a hardware limitation or a driver problem, but it will only support ONE device at a time. I cannot even use a matching keyboard and mouse set together! My other Bluetooth dongles can support at least 2-3 devices at once.

Other Thoughts: If I try to connect a second device it gives an error saying "connection failed". When I tried it on another computer without installing the BlueSoleil drivers, Windows said there weren't enough channels available to connect a 2nd device.

Bottomline: It's fine if you only have one device, but not much use otherwise.
