Use for many years Logitech mice, since always been satisfied. After intensive use but even these go sometime Decrepit retire. Therefore, these ordered here again and fully satisfied, fits comfortably in your hand and just works fine. Simply connect and start surfing. Processing is also fine as rattles and crunches nothing. The cable length of nearly 2m should be sufficient even each, otherwise you should buy a cordless. Although practically but I just hate when the batteries are all in the most inopportune moments. Therefore, I stay in the prior pc wired mice.
