M700Pro

FWIW I've stopped paying premium for big brand mice. Last one was a Razer viper V2 that lasted less than 6 months and started having scroll problems and RMA/Warranty was denied. You can get same if not superior quality from less known (often chinese but not necessarily) brands. I'm now using a Delux m700 pro mouse that is kind of a clone/same ergonomics of the Viper V2 and I'm pretty happy with it.

As the other guy said Model O2 pro or if you go with the Viper get the Viper V3, not v2 Or if you want to go with Chinese OEM you can get **Delux M700pro** which is almost 1 to 1 copy of the Model O shape but with better internals
