I have one and if you use a Mac they're interface is THE WORST! RealTek is the driver and either Microsoft pays their programers or their programs don't know anything about programing. The interface for the Mac is about 50% of the quality of the PC. On the Mac you get basic info but nothing on signal strength till you connect. On the PC you have signal strength listed for every AP. On the Mac once you connect you have a silly bar showing signal strength and then the number representing said signal. On the PC you have two bars with numbers showing signal strength and quality. They did update the Mac driver about 6 months ago and added the signal strength number. Don't know what else is under the hood but that's my take. Good Luck!
