Was that your first guess?
G-Wolves has been around for several years and has released a number of gaming mice and accessories like high-end mouse feet and non-slip stickers. The Hati-S Plus 4K was released fairly recently, and part of its name comes from his 4000 Hz wireless polling rate that it offers. The polling rate can be lowered if desired, but it drains the battery severely. That’s why G-Wolves put a pretty heavy polling rate on the Hati-S Plus 4K. If you need a specific size grip tape or mouse feet, the mouse comes with a number of accessories.
Inside the mouse is PixArt’s PAW3399 sensor, which can be adjusted up to 20,000 CPI, and a Zippy DF3-P1L1 switch. TechPowerUp impresses with its minimal click delay, precision sensor, and lack of motion delay. However, this quality comes at a price. The mouse has a MSRP of $160.
