I've been using the Superlight 2 for about 6 months now, works fine and is what you'd expect from Superlight 1 but with a few improvements including usb-c and 4K polling rate.
Although I had to dissasemble it and clean the mousewheel as it accumulated dirt which made the scrollwheel cancer to use and kept scrolling up or down when using.
Razer Deathadder V3 Pro is a decent alternative.
