Summary: Bought this after a lot of research on the web. Very sleek, responsive and comfortable mouse to use. It stood up to all of the positive reviews that I read, but has not (as yet) lived up to any of the negative reviews! You speak as you find!!
Summary: Excellent Logitech mouse for use on the move - e.g. with an ultraportable laptop/ netbook. Roller wheel is depressable for 2D movement and tilts to left and right for sidewsays scrolling. Central button can be set for special function (default setting toggles through open applications). There are two outstanding plus features: (1) a little stud which attaches to the lid of your laptop and on to which the mouse fits for transport.
Summary: This cordless mouse is very well thought out, practical, classic looks, compact & well made. I already had a "cordless" mouse with my work laptop, but as I travel extensively and use it in hot-spots & airport lounges, I found the 1m cable to the "wireless" desktop transmitter caused more clutter & tangles than an old fashioned wired mouse - and I had to plug in the transmitter every time I moved.
Summary: This mouse is great. Delivery was fast and prompt. The responsiveness on different surfaces is remarkable and battery life is unbelievable. Really love the change of the function of the middle mouse click button as it used to get in the way when playing first person shooter games. A must buy for people who are really into there mouse. My hands aren't that large and the mouse feels great in it.
Summary: I wanted a wireless mouse for a while but instead of spending a little extra, I initially bought a cheap one. What a mistake as it broke within a couple of weeks. Due to this I decided to spend a little extra a get quality Logitech, i am glad I did. This mouse is wireless, reasonably priced and convenient + the usb is so small I didn't know where it was at first! It also contects to your laptop when not in use - excellent.
