After my Microsoft Standard Wireless Optical Mouse had given up the ghost, I opted for this mouse. Compared to my old mouse, this is much shorter and flatter and is therefore not good at (ie in my) hand. After an evening of intense computer work I had thus pain in the hand. The scroll wheel is smooth, which leads the middle click that often the scroll position is not changed when you click. The surface is smooth, shiny plastic, also the mouse for my taste a little too easily. The feel is overall rather below average and seems cheap. That's not what I hoped for from a Logitech product. On another PC I use a Logitech M310, this is ergonomically so much better than this. I will return this mouse and try another product.
