ZIYOU LANG x Attack Shark R2 Wireless Gaming Mouse, Ultra Lightweight Magnesium Alloy, PAW3950 42000 DPI Optical Sensor, 8KHz Polling Rate, BT/2.4G/Wired Programmable Mice with Grips Sticker (Grey)

At first, I loved this mouse. It has a very light weight and a good feel, and the provided grips are nice (comparable to the Pulsar supergrips). Then after a few days, I got a random disconnection while gaming (oof -- in a ranked game too!) Had to reset the dongle and power cycle the mouse, and then it was working well again. After about an hour or so, the same thing. After seeing a YouTube review having the same issue in 8k polling (I'm currently using 4k polling) I think it may be an issue with the mouse itself. It's a bummer too, because I liked this mouse until the issues. I think it's time to go back to my Razer Cobra Pro which is a bummer since I really enjoy these optical Omron switches more.

Great working mouse. It’s fast reacting and doesn’t have loud clicks.
