Summary: I was given one of these for Christmas, because I was always complaining about the fussiness of my previous laptop mouse with regard to the colour of the surface being used that the mouse wouldn't work on. It really is fantastic! It will work properly on any surface at all, be it plain, coloured, patterned, or even glass.
Summary: I've had this mouse since Christmas and it's had more or less daily use. It's nicely weighted and performs excellently. With rubberized sides, you feel completely in control with it's reassuring left and right solid clicks. Scrolling is again perfect. All features of this work as you would expect and I would not hesitate in purchasing another should the need arise.
Summary: This was to be a replacement for the M185 that did not work. I have two of these mice at home and they work fine I would not be without one, However this one was to be for the office but was completelly dead so sent it back for refund. The M235 was a replacement,this is also dead, in-spite of the Bateries being fully charged. so I thought that buying a more expensive model would be better. Wrong so now I have to find an other type.
