I have one. I like it, I find it much more comfortable than joycons in handheld mode, and the buttons are more like a pro controller (compared with joycons and grips like the Satisfye). It feels more stable than the Hori Split Pad since it goes beneath and behind the screen, but it does add a bit more bulk. My only complaints are that the LED is on by default (you can turn it off but will turn back on after waking from sleep), and the release button can be a bit hard to slide.
Yoku’s Island Express might be up your alley- it’s part platformer, part pinball, and it’s on sale.
