5 out of 5 eggsAsus BT USB

Pros: Plugged it in my Mint system. Works for my PS3 controllers and BT gaming headset.

Cons: Other reviews on here suggest to use with an extension. I recommend the same. Wouldn't recognise anything while being hooked up direct. I have no idea why. Just happy it works.

Other Thoughts: Worth the cash.

4 out of 5 eggsThe only BT 4.0 adapter I could get working with Windows 7 desktop

Pros: Works with Windows 7

Cons: Setup still requires some trial and error in Windows 7, especially if you had other Bluetooth adapters/stacks installed previously.

Other Thoughts: I tried A LOT of Bluetooth adapters on my Windows 7 desktop. Most never worked. Some would work initially but disappear on reboot or days later. Nothing with a CSR Bluetooth stack would work reliably. The ASUS USB-BT400 with the Broadcom driver and Microsoft enumerator is the only config that's been stable.

1 out of 5 eggsAvoid!

Pros: Cheap, easy to install

Cons: Had to download drivers from third-party website to get it to work (ASUS didn't have the drivers available). Literally fell apart while plugged into my USB port. Thought it was bad luck and bought another, but the same thing happened.

5 out of 5 eggsnot sure why so many poor reviews...

Pros: works, all the features, all the time. the coverage footprint is even bigger than I thought it would be. it's always over-exaggerated in the specs, just like wifi...

Cons: the sale ended before I could get another one...

Other Thoughts: skip the included software (that's usually sound advice for most computer and related devices). go directly to Broadcom (the actual chip designer) and get the latest software / drivers and roll that beautiful bean footage.
