I'm a owner of a Logitech G602, ex-owner of a Logitech G700 and I also had a Razer Mamba. As much as using wireless mice on my laptop is nice, there's no denying wireless mice are worse.
Having to worry about battery life, having sub-par sensors, bad performance on many cases, limited options, range problems (especially with the G602 which has only 3m range) is quite annoying. If you use a Desktop, buying a wireless mouse when you want performance is a plain bad idea.
I also have a Matias Secure Pro, but being honest with you, I prefer using the Mini Quiet Pro on my Desktop due to the following reasons:
- There's no risk of me leaving it powered on and there being no battery left when I come back (there's a huge flaw on the wireless sync system on the Matias Secure Pro)
- The USB HUB actually works as it should on the Mini Quiet Pro.
But sure, if you want to connect your PC to your TV or move your peripherals around, wireless can be nice, but I really wouldn't say it's better.
