Summary: I love my mouse- my only complaint is the usb plug in part- i dont know what they call it- it sticks out a bit from the side of the computer and is easily broken- this is my second one. I will buy it again too but I wish they would redesign that part and make it smaller. It has excellent responsiveness which is important because I use it on the arm of my recliner and use my laptop on my lap. I dont use a desk or mousepad so this is important to me. Very nice mouse.
Summary: I've been using this mouse for about a month, and it lives in my travel case for my laptop which gets some pretty rough use. The mouse has worked flawlessly every time. As for the reviewers that haven't gotten good range... I don't know what to tell you. Mine works from across the room. I did DL the latest drivers from MS and am using Vista; perhaps that has something to do with it. Overall, batt. life has been good, and I am very happy with the mouse.
Summary: This is the second (and LAST) of 2 Microsoft wireless mice that I've purchased. Don't ask me WHY I bought Microsoft again... maybe I was giving them a second chance. Big mistake. This mouse was not a good shape for my hand (and I have normal hands, they aren't freakishly big/small) and the USB connector was always having trouble "finding" the mouse that was practically sitting on top of it.
Excerpt: I bought this laser mouse during a special promotion in a local computer store at a bargain price of RM 115 (around USD$ 33). As it was relatively new at the time of purchase, the normal price was supposed to be around USD$ 40. It was my first laser -powered mouse. This mouse is highly precise and responsive, thanks to its High Definition Laser Technology. The tracking is quite smooth too but it does not behave very well on glass and highly reflective surface.
Summary: When photo-editing on a laptop, a mouse gives better control than a touchpad. This is a great little wireless mouse to put in your laptop case. The USB receiver is stored in the base and switches off the power at the same time, so the batteries last for ages - great!
