Works great when in front of computer, connects to both the blue tooth and computer with no problem, but continuity is disturbed when we move a 3 to 5 meters from the source. If we stay at that particular distance for a while, it gets signal at random, and there is some direction/height combination to get it work. I have not gone through the documentation to find out the max range it covers.***************************************************************The above was a previous feedback from me. Now the situation changed. The below is the recent drawback I noticed on this headset. I also wanted to change my rating to 2 star or less.I bought this phone around November 2007, and the phone was working fine till March of 2008. Recently this phone is not being recognized by my PC (Windows XP home edition). When I tried to update/replace the driver for (Dell wireless 355 module with Bluetooth 2.0 EDR technology) the bluetooth service, all my efforts turned vain, and was getting the error, License expired for the bluetooth device, and tried at the WidComm's site for the updated driver but also of no use.So this bluetooth headset is now a regular headset, with a cable, shorter than those of regular headsets (and this headset also cannot be used without the cable that came with the package).I informed you well in advance before you buy; Hope this helps.
