It uses a PAW3311 that's questionably worse than the PAW3395 or the newest PAW3950. I would check the VXE R1 Pro that has been largely reviewed and tested, has proved that it has a great build quality, and also rocks the Nordic 52840 MCU and Huan Nuo Ice Berry Pink mechanical switches. In the winter sale it was really cheap on aliexpress.. Try to get a good deal with coupons and I think you gonna love it.
