UPDATE: After I posted my review (see below), TeckNet contacted me and said they would refund my money, which I didn't. should return the mouse. I knew a reply letter would come. and it arrived today. YOU WANT ME TO CHANGE MY PLAN TO FOUR OR FIVE OR REMOVE MY RATING. Of course I won't do that. I used the mouse for a few more days and it went down even more, now it beeps when I press the left button. I threw it in the trash this morning. DO NOT BUY TECHNET PRODUCTS. Initial review (unchanged) When I opened the small box, inside was a small mouse-sized bubble wrap followed by a mouse (not in a bag). It's like someone opened the box and used the mouse, then put it back in the box and gave it back. It's a cheap mouse, and the CLICK is LOUD, and an even more bizarre electronic hum comes from the nano receiver. For the rest it works. I had to get an X mouse to be able to control buttons, speed, etc. come back {sigh}
