Despite the brand new feets and all the care you can imagine, my mx518 just died:( I tried with a new wire, but it's dead. RIP

I dig up my old Mouseman Dual Optical (m-bl63b) in one of the boxes from the cockloft, I cleaned it and it's in pretty solid and good shape, looks like they made some quality builds that time.
The feets came off(?) after the first few moves, so I polished (leveled) the bottom with a 1500 grit sandpaper, and installed some G5 Hyperglide skates. It glides very smoothly now.

Tbh I had absolutely no clue about gaming mice when I bought it. It's still working flawlessly, but acts really strange sometimes.
Does anybody knows anything about this mouse? It's not included in the Esreality mousescore, and I wonder if it's worth it to overclock to 1000Hz or perhaps 500Hz is enough, or does it skip above a certain amount of speed ...etc.

Any info would be appreciated, but I will also try to google-up as much as possible.
