There are mech mouses, as in with a ball still?
No mate. Luckily the ball shall never return :)
The 'mech/mechanical' part is the keyswtich. It's not feasible to put a mech switch in mice. yet...
The days of aesthetic mice are largely over, but luckily ergonomics are not. My Thermaltake Theron looks ugly and awkward, but is actually the most comfortable mouse I have ever used. There is a mouse for everyy hand. Finding the right one is the tricky part. One size and recommendation does not suit all.
And don't get me wrong folks, I'm not saying 'you're doin' it wrong' because you use membrane boards. I'm a strong advocate of it does the job, no need to replace. (Advice for others, not necessarily myself
)
Some membrane keyboards are lucky that the rollover is not near WASD cluster and thus does not impact gaming etc.
However others (like I've had) have been deal breakers. It's down to the PCB (printed circuit board). I'd suggest a new mouse over a cheap, yet comfortable and working keyboard. Again though, if you are content with what you've got - enjoy it.
But - when you've upgraded everything else and are looking for a new avenue of improvement; have a look at mech boards :)
Tbh, when it comes to peripherals, ignorance is bliss.
I personally notice the differences most people don't. FPS latency, FPS over 30/60, micro-stutter, input polling rates, failed key registers, wireless lag etc
I can easily notice the difference between a polling rate of 125 vs 500. 1000 not so much. I can also notice the almost imperceptible lag a wireless mouse has over wired. Same goes for n key rollover. But if you're lucky enough not too notice, then I envy you.
I've spent
far too much finding what suits me. But at least my findings can hopefully help others.
