I really don't remember model number, it was somewhere between 2009 and 2012, it was Logitech, it was laser gaming mouse, shape like mx500.
DPI is the answer - Optical (red led) have smaller DPI, laser (no visible light) have DPI up the roof bcs marketing. You could think higher DPI is better but... More DPI = more data to transfer trough mouse CCD and mouse internal CPU. While mouse CPUs can handle that without problem, CCD is "bottleneck". With those super high DPI, CCD picks up a lot of invalid data.
Think about it like about camera with really crappy CCD (1.3 MPix), doesn't matter how good light you have, if you move during doing picture, you will get garbage. Sure there is picture stabilization, and CPUs in mice use that. But when it comes to mice its more like trying to rescue burning house with bucket of water, will help but not much.
That's why some ppl prefer optical instead laser, lower DPI = less garbage data = no jitter.
You know, HP which is producing mice wont have their bias in the middle, i mean, ofc they will glorify laser which is in their products, bcs they can put bigger price on it. Sure, 16K DPI looks fantastic on the box, super marketing, but show me at least 1 person who plays games with DPI above 5000. Heck, most ppl stop way below 3000.
I started with some BTC ball mouse, had scroll wheel, PS/2 connector, then i had A4Tech optical wireless mouse - was ok besides being wireless (battery made it heave af). Next was some A4Tech gaming optical wired mouse, served me well for many years. After that i had 3 mice of Logitech, all 3 were the same model, laser and gaming - i said never again Logitech, time for Microsoft - optical, wired, 5 buttons - was perfect. Atm Lenovo M800 - jitter like bloody hell...
I don't say wireless can't be good, but i wouldn't trust so much in Logitech, HP, ASUS, etc etc numbers - it's marketing. In my case wireless is a big no no bcs after 10-12 hours of work as an electrician i don't wanna drag heavy mouse bcs it have battery inside.
Anyway, subject is pretty much closed as Bambacha show me Zalman mice, i pick ZM-M201R which is wired optical 1000 DPI with 5 buttons mouse, already ordered (fun part was that yesterday english page didn't show me mice at all, had to switch to korean), so i guess this forum subject can be closed.
Thank you guys for time spent on this subject and writing replies with personal experiences.
