I have been a fan of Logitech mice for over 10 years and have become accoustomed to their build quality, reliability and comfort. I use an MX 1000 on my desktop and so last week, when I acquired my first laptop, I immediately began looking for a suitable mouse. The Logitech VX Revolution stood out head and shoulders above the competition.
It arrived yesterday; I installed the drivers, plugged in the dongle and everything worked perfectly first time. Despite its 3/4 size it is a pleasure to use, the supporting software allows customisation of practically all the buttons and other things besides - and the new 'free-spinning' wheel is great innovation. (I'm told that some people are still using mice whose wheels don't even rock sideways!) All in all it's a beautiful mouse, cleverly designed and well made.
If you need a laptop mouse, can afford the investment and are prepared to pay for quality then you'd be very hard pressed to find a better way of spending your money.
