Class 1 - 100m range Class 2 - 10m range Class 3 - 1m range I've never seen a class 3 device, and although I do have a class 1 controller it doesn't seem to make much difference as to signal quality at close range (I guess its just more powerful radio). Then there is Bluetooth version, so you might see v1.0b v1.2 v2.0 + EDR v2.1 + EDR If you see a v1.x device for sale then don't be tempted. v2.x devices are vastly better at making and maintaining connections, and the 'Enhanced Data Rate' gives much faster transfers. I've not seen a v2.1 dongle in the real world though they may exist (ditto for v2.2 as spec is availabe) I have seen (recently!) a v1.0b device advertised as "BLUETOOTH CLASS 2" with the v1.0b in really small writing on the case, I guess that these are old stock dressed up to sell rather than new manufactures but its good to be aware :) iain
