It's fine, not amazing, but I love it for the fact that it's a very condensed southpaw with the F-row. Exactly the layout I want on a board so there's not many other options.

The biggest quirk to get used to is when reaching for Ctrl with my left pinky, I sometimes press the numpad enter by accident - I put a box navy in that key so I have a safeguard compared to the other speed switches.

The software is clunky and mistranslated, no QMK support, but it's been good at remembering to stay on my custom layer - the primary one can't be changed. Really difficult to figure out custom LED patterns/colors.

If you like modding boards it's certainly one that can be improved in a lot of ways - filling the case and taping the PCB is easy enough, but I don't like the plate it comes with so I designed+lasercut a new one - that's still a work in progress though.

The Q12 would honestly be the best option if you just want a really nice southpaw out of the box, but it's way chunkier than the gk96.

I have the same board, to mimic arrows on the right-hand side you can press FN with your pinky and use the other 3 modifiers with the ? key for Up. FN + WASD also works, as well as Numpad arrows!
