The mouse is super easy on the hand. I ordered the mouse because ordinary mice now cause me a pain in his hand. With this mouse you notice immediately how relaxed it is to handle. At work I have a vertical mouse. The loose three times as expensive but not as comfortable as these. For the price a great deal. Will keep the manufacturers definitely in mind. If so offering a kind mouse in the higher priced, I'll be there certainly buy me one. The dealer himself is also top. Fast shipping, fast service.
