Review on Logitech M220 Silent Wireless Mouse, Red by Jnis Griis ᠌

Runs very quietly (as advertised). Tested in various conditions - very reliable. The only minor inconvenience that I encountered is that one AA battery (or, as they used to call it, 316th) is required. Now this is rarely used where it is used, but they are usually sold in a set of at least 4 pieces (in a smaller amount, maybe they are sold somewhere, but I personally have not seen it).
