Similarly, even the higher-priced Logitech mice often use tact switches that are only rated for a relatively low number of clicks (probably 1 million?), so many of them started failing on me after about two years. Replacing the switches with higher-rated ones (50 million clicks) is trivial on all the mice I have disassembled so far. The switches and replacement glider pads (which need replacing after removing the screws hidden below them) are often just a few bucks but make the mouse last for several more years.
