Summary: A good quality but competitively priced mouse purchased to replace an earlier and slightly different model which had deceased after years of use. Logitech tend to be decent quality and as I am not a gamer, anything over 1000dpi is a waste of technology for me. The wheel can be a little noisy of used for lengthy periods but other than that, it is great to use left handed (as I need it to be) or right handed as 90% of people reading this will be.
Summary: Nice touch and a nice white colour to match other 'non-black' accessories, ie. white tower case, keyboard and speakers. It actually came with software to configure the scroll wheel to double click. Only gripe, is that the wheel 'clonks' instead of 'clicks'.
Summary: Well, this mouse is perhaps not the best and most high-tec unit with more functions than can be counted, but it is very good at the price. If you need a cheap mouse, this is THE ONE. I have been using it for several years now, and it still works fine. It might "die" very soon, but that would be very understandable as I bring it to and from school in my bag every day (and that beats it up pretty bad). This doesn't make it any worse.
Summary: I chose to give it a 4 because the mouse (for its price) is good, but the drawback is that the design is somehow dodgy and can be problematic for people that are used to different kind of mouses (talking about the left and right mouse buttons and how there's a separation from the sides which is annoying for me).
