Strong recommendation for Cyclone 2. I've been so happy with my first one that I'm about to order a second one.
Excellent ergonomics. The RGB you asked for. Works perfectly with my CachyOS and Bazzite setups out of the box. Premium metal charging stand included. Excellent clicky switches including changing triggers to micro switches. Hall effect triggers. TMR sticks. 2 back buttons.
This is available brand new on eBay for £30 in UK. You won't be disappointed.
