Bests & Worsts Reviews from Amazon

I own 2 other Tecknet Mice and they work great. I just purchased the TECKNET Bluetooth Wireless Mouse for my DJ laptop and WOW, can't tell the difference from USB wireless to the Bluetooth... But this 2.4ghz that I just rec'd this afternoon... not so much! DOA.. put in 2 sets of batteries and nothing. Light wont come on, the computer don't ding when I plug in the USB dongle... nothing.. I guess 3 out of 4 aint bad, but I guess I'll look at a different brand now. BUT.. it does feel awesome in my big hands! ******* UPDATE... tried a third set of batteries and a different computer and it works just fine... My USB port must have an issue... but all is good... 5 stars!!!!
