Having read some of the reviews for other Bluetooth adapters out there, I was a bit reluctant to get a product from a relatively unknown maker. I'm glad I gave it a chance!I installed it on my home XP Pro (SP1) system on a USB 1.1 (powered) hub! It installed in minutes, and a couple of clicks after that, I was synchronizing my iPAQ 2215 via a bluetooth connection.
This item comes with short USB extension cable. I won't use it since I think it's safer to have the adapter securely plugged into my hub, but I do understand why some people may find it helpful. The adapter itself is very compact, and it doesn't take up more than its share of space on my hub, thus allowing me to use all the plugs next to it.
There are two versions of the latest software for this model, depending on your unit's serial number... Make sure to select the correct one if you download the latest drivers.
There isn't anything special about the design or looks of this small adapter, but so far it's worked perfectly for me. I don't know the exact distances but I've been able to connect my PDA from anywhere in my apartment.
I hope you have a similar experience to mine!
