Do you have a favorite mouse you happy with? A mouse which gives you good and stable competitive performance. A mouse that don't f_cks your brain and works stable on many surfaces.

Then.. why changing/replacing it after it broke?

The most problematic things in mice are:
1) microswitches
2) wheel
3) cable
4) body

The body is the most reliable part usually from that 4. And the sensor is almost immortal.
Changing cable is so easy even your dog can do it.

And about microswitches and wheel, you can replace it easily in 10-20 minutes. And more, omron are not the best ones and not fault-free. I've seen some chineese that works for 8 years of regular and hard using w/o any problems. You can order it or even find it for free easily.

So.. I'll find a mouse that I would be happy with, buy few examples and would use it 4life repairing it if it broke.
It can work even in 2016 for WMO. Buy few (even used) on ebay and repair it if they broke => WMO4LIFE. And who da f_ck cares that it was discounted years ago.
