So. I have 2 I hate.
I had this old gamesube one for the switch. It was a wired one by powerA. Buttons would get jammed, accidentally broke the stick by leaving it in a bad position overnight (my bad) the cover of the cstick randomly slid off (had to glue it) and the while thing was hollow.
Also, I have a keapster explorer and the dpad is awful. Sometimes it jams to the left but its just a plain bad dpad, no physical feedback at all
Single joycon is barely usable, but the Wiimote was terrible for sideways holding.
Its shape was clearly never intended for it, and the d-pad was absolutely awful, one of the worst I’ve used.
The d-pad worked as buttons (which was how most games used it, in vertical mode), but for movement it was very stiff and almost impossible to get diagonals. For a console that featured virtual console heavily and needed a lot of classic controls, that was very bad design.
