I have used quite a few of those little Bluetooth dongles and have never encountered one that didn't work. Even ones that I purchased from Hong Kong for 99 cents each. The more expensive ones are probably a little more durable but don't seem to work any better. I've never had to load drivers from a disk, very few of the dongles I've used even came with a disk. I just plug them in and Windows finds and installs drivers for them.
