Sure, but do you need five gaming mice? No. You need one gaming mouse. Which will last a year, so you're buying a new gaming mouse every year. Which means you're getting used to new ergonomics every year. Which means you're throwing away a gaming mouse every year.

I've had a Logitech MX Revolution since 2007. It cost me $100. Amortized over six years, I'm paying $16 a year for it. And I'm not filling landfills with dead mice and dead packaging. Not only that, but it's a sweet fuckin' mouse. It's supported by everything, has all sorts of macros I don't use and a frickin' weighted flywheel inside which comes in damn handy in Pro tools. I oughtta replace it - the paint is worn off the side and where it had "grip" it now has "shiny" but it still works like a champ, still holds charge for two weeks, and still fits my hand quite nicely, thanks. Would I trust a Monoprice mouse? Nope, and I own a couple. The difference is instead of buying them off Monoprice I bought them at a night market in Bangkok for 300 baht each knowing they were cheap chinese shit. It's good to have disposable mice around.

The mistake is in thinking that 'disposable" isn't an adjective to describe Monoprice's stuff.
