"At $45, this is a fairly small investment, but can also serve as a good introduction to custom mechanical keyboards, including working with custom firmware as it uses QMK and supports VIA. There is one thing about the Super 16 that is important to know, and that is it also supports per-key RGB LED backlighting. That does mean you can have this be just as flashy as many "gamer" keyboards today, but you do need to solder these RGB LEDs in, and that is not the easiest process. Fortunately there is also the Sweet 16 from 1Up Keyboards that does not support LEDs, but is also a bit cheaper. Having only learned to solder for this build, I did not attempt to install the RGB LEDs, but watched closely as my father with his decades of experience did so."
