Excerpt: The Microsoft Explorer Mini Mouse comes with Blue Track technology. It fits comfortably in the hand and has a groove on the left side to accommodate the thumb. This nifty little mouse also sports two buttons which act as internet controls.
Summary: Replacing identical unit received as present; previous one used too much battery, retainer piece on bottom lost its ability to stay secured, and finally began to not move the cursor properly some of the time. New one works fine, we'll see on the other things. My experience with ordering and delivery was very good, which accounts for the five star rating.
Product delivers what promisses but it is bit larger than I would like to...

Summary: Overall rating: good quality product and nice design. 1) it was delivered on time; 2) the package was damaged and did not look like a new product but the item works perfectly; 3) neoprene sleeve to carry the mouse surprised me positively; 4) it could be a little smaller as I use it with a laptop.
Summary: This mouse looks very impressive and feels good in the hand, but the transceiver has to be removed from the pc to turn it off. The transceiver's home slot on the bottom of the mouse is shallow so when stored it stick out. The mouse can't sit on a flat surface and the transciever is subject to being caught on clothing or lost. Which is what happend to mine after only a month and Microsoft has no way of replacing the transceiver.
Summary: A travel (laptop) mouse need two things; the ability to read on any surface (which this one claims to have) and a small size (this "mini" is a standard size mouse; even larger than some standard desktops). A third benefit is a short USB transmitter; this one has a long one.
Summary: i ve purchased it last year, so bascially i used one year, then it just crashed out. i feel frustrated, i dont know whether there will be some help offered from the wedsite. it sucks that now i m in china, i want to know whether i can take it to microsoft shop to get repaired. i kinda like it.
Summary: I use this for CAD design (and everything else). It's fast, smooth and has enough button options. This is my second trackball explorer (I use one at work and one at home). I've used the Logitech cordless trackball, but its buttons and overall size are too small. I wonder if Microsoft stopped production on these because they were infringing on a Logitech patent.
Summary: I purchased this in 2001 and am still using it. The layout of the device is brilliant: two buttons (left/right click) and a roller under the thumb, fingertip control for the ball, and two additional fingertip buttons. I have them mapped to page up/down, which makes moving around web pages effortless using only the trackball. No other trackball made has this unique combination, unfortunately. They either put the ball under your thumb, or omit the fingertip buttons.
