Excerpt: If this mouse would work forever like it does when it's new it would be great. The problem is that I've owned 3 of them and every single one eventually broke down and didn't work correctly after some time of usage. The scroll wheel is def an issue on these mice. It will kind of have a mind of it's own sometimes and not scroll correctly. Another problem was the pointer moving around when I wasn't moving the mouse at all.
Summary: I bought this for my wife to use with her computer, and it works so poorly I may send it back, we have tried various mats but it is very erratic and sometimes refuses to work at all, We are very disappointed with this as I have never ever had a problem with a Logitech product before
Summary: I'm on my second purchase of this mouse now. The first suffered from being in my bag and the mouse buttons got done in. Also the wheel became sluggish and middle button not so good but I put this down to the abuse of travel. So liking it a lot and cursing my own abuse of it I bought a second one, got a box to keep it in to keep it safe unlike last time and thought that would be me happy. Except no, the mouse wheel is getting sluggish again.
Summary: I like Logitech mice as had them before so I bought this one in December last year. It came to hand nicely and still does but unfortunatley it is very unrelaible with it's click ability. when you click on something or just to move the curser in a document you may have to click 3-4 times or bang it on the desk to wake it up. Not a good purchase I'm afraid.
