After I've done some mice at my PC, I wanted to set this Logitech M525 me. As might be expected, fast delivery, stable packaging, so perfect. The handling of these medium-sized mouse is simple and logical, fits perfectly in the hand and is easy to carry on the mouse pad. The buttons and the scroll wheel to react quickly and reliably. Especially practical is the mounted slide switch under the mouse to save energy, which undoubtedly prolongs the life of the batteries. The micro receiver can be stowed in the mouse for easy transport, so you can take them on trips. I would buy this mouse again.
