Kone Pure Ultra

Im trying to find a mouse that can butterfly click good, and have 4k polling rate so I can also use it for other games. What do you guys use? I was thinking about the Glorious O2 Pro 4k-8k but I heard it has issues and it's not better than it's predecesor, the Glorious O. I've used a roccat kone pure ultra and I'm not the happiest with it, then I switched to an Aqirys Polaris which is not much better.

My setup is basic, but since you said Endgame, my setup is the Anne Pro 2 with cherry MX browns and my mouse is the Roccat Kone Pure Ultra

Changes often. The past few months it was the Viper V2 Pro. Before that it was the Kone pure ultra

I have a Roccat Kone Pure Ultra and love it

My anecdotal experience, my kone pure ultra started double clicking. I submitted a claim to warranty and had a brand new replacement in less than a week. I've been using the burst air versions for years now with no issues (optical switches shouldn't develop double clicking) Turtle Beach bought them and killed the brand off, still making things but under turtle beach name now
