So do I!
So, I only have the money to buy the console, screen protector and a case.
I have did nearly everything to see if my Switch has problems or not.
I checked if my Switch is warped, left joy con desync, dock scratch etc.
And I do feel that Switch is pretty heavy but it feels pretty comfortable, I feel the grip is good to hold as well. The one joy con though, needs to get used to a bit. And the dock does scratch the screen, but I have my screen protector so that's not an issue.
I did almost the same thing, and you guys may be surprised but I actually found the right Joy con to have minor desync, I mean only minor desync when I went about 4 meters away (My dorm is small) and put joy cons on my back . Left Joy Con has no desync whatsoever in the same condition.
So far I am safe to say my Switch is 90% normal, I haven't got any game so I don't know if my Switch reads game perfectly or not.
