Excellent when working, but brakes up very quickly
on 28 July 2013
When working, this is the best mouse one can find on the market and currently the only one of its type that is commercially available. It can be verified by Amazon that I've gone through 4 of these mice in less than 2 years, which is the problem. There are lots of people complaining about this device on the internet - after a short while, the left button stops responding properly, which renders the mouse useless. And for £50 a pop that is not good enough. My Microsoft thumb mouse, which is now discontinued lasted for more than 10 years. I hope that someone from Logitech (to whom I've written about this problem) reads these reviews, so they can take action - to me at least it is obvious that there is a quality problem with some parts of this mouse. The only reason I keep purchasing it is that there is no alternative to this product.
