Just for the record, while I do use a Duke Hyperkin controller, I can use normal sized controllers without cramping up constantly, so I don't think it's just about size. Of course, there's no way to find it now, but shortly after the Switch came out there was a fairly sizable discussion on the main site in the comments of a Nintendo article about how uncomfortable it was to use, which was why there were so many covers and such that you could buy for it. I did buy a cover, and it made it somewhat better, but didn't completely solve the problem.
