Didn't get any new mouse in the recent years. From the ones I've tried, two were very good (not sure if they are still in production):
- A4Tech wireless mouse G9-730FX (sometimes sold as a pack, together with a wireless keyboard). The wireless range was very good (was still working from a nearby room), decent work on almost anything, but most of all, it was still working when slightly lifted, which made it very good at controlling a PC from bed, using irregular surface of pillows and sheets, or in the field, where you may still need a mouse, yet there might be no flat enough surfaces around you (e.g. in industrial installations).
- Another memorable mouse was the Logitech MX1000 Laser Mouse. It was using an IR laser diode instead of the typical red LED that illuminates underneath. That made it able to work on almost any surface, including on glossy glass or mirror surfaces, but it was not working when lifted more than a few mm above the pad (so not very good to work on improvised surfaces that are not flat enough).
