I'm currently use this one on laptop with Windows XP in pair with Ezurio dongle.

Pros:
- Good coverage range
- starting and discover devices much faster than my older dongles
- fast transfer speed
- easy to install and use
- affordable price

Cons:
- it's working under Linux but because firmware contain a bug which make this dongle to be detected as BlueTooth v1.1 This could be fixed but only if you're not afraid working in console. Such problem doesn't exist if you're Windows user.
