Summary: My biggest complaint is that when I port it between my two computers, I need to reinstall it each time. This does not take long, but in the world of plug and play in which we now live this is annoying. Otherwise, once paired the device functions impeccably.
Summary: This ASUS bluetooth works on linux also. You just need to install the Ath3k driver for your distribution. Actually, the chip is from Atheros series 3000 and has USB2.0 connection but is not so fast. You get around 80KB/s transferring files between PC and Mobile with 100% signal strength.
Summary: I bought this dongle to be used with a Hackintosh build, if you're not going to do that then the rest of this review is irrelevant. If you're going to use this dongle on a Hackintosh build consider this: there are other better supported dongles out there.
