The size is just right for my small hands. I bot two. the first time I hooked up to a computer USB port about five feet away from the mouse it didn't work well at all. USB was on the side and away from the mouse. I placed it in the back and a foot closer and all is well.

Love it.

Microsoft has a real winner with the Mobile 4000, it fits great in the hand and its wireless. I highly recommend it.

Highly sensitive; works on almost any surface; nano transceiver

I love this little mouse. I use it with a laptop setting on a laptop table. There is a little space on the table next to the computer, not enough for a full size mouse, but enough for this one. The main thing that I like about this one is the back button.

Compared to the price you pay, it is good purchase. Its looking from the picture is better than what really it is.

This is a small mouse but is easy to use. The USB attachment is tiny and can be left in place. Only downside is that the mouse must be switched on before the computer is fired up or the USB toggle removed as otherwise it seems to cause a problem with the start up with my computer running windows 7

I've been using this mouse for three weeks now and it's very good. I used it even on reflective surfaces without problem.The fourth button can be configured to execute custom command, but only one. I use it as AvPag, but can be any key or key combination.I recommend it.

I've used this wireless mouse for 4 years and it did work well. Proper size (not too small), light weight (only needs battery x1), smooth scroll wheel and great last page button on the left side of the mouse.

The only issue I had with this keyboard was the compatibility with Windows 7. You can download the driver on the Microsoft website, so it's no big deal. I love everything else. The wrist pad is soft, the "my favorites" buttons are awesome, and the zoom button in the middle is useful.

Comfortable Design; Easy To Clean; Great Features; Quiet; Reliable Performance

Limited Compatibility

WHAT A wireless mouse for use with any laptop, computer or device that has a USB port and capacity for a mouse to be used with it. It does more than a standard Microsoft mouse so is priced higher at ￡25 but the extra features make this a worthwhile way to fritter away a purple note.

Good stability; useful extra features but does remain a basic wireless mouse

Not the long battery life promised by Microsoft
