Already, after less than 3 months, I have experienced a bent dock, scratches on my screen protector in the bezel area, plus my L and R Joy-Cons have chipped latches. I also think the right side of my Switch is slightly warped, but not excessively so.
Thankfully I had a screen protector that protected the Switches bezel area, but I bought a new screen protector and a dock "cozy" to protect the Switch further.
As for the Joy-Cons, without me dropping the Switch or the Joy-Cons, those latches already wore out making it impossible for them to lock on to the Switch.
Thank goodness I am under warranty, because I sent the left Joy-Con in a few weeks ago and now just today I contacted Nintendo to send my Dock and right Joy-Con in.
I so wanted to buy one just for my 8 year old son, but after all these issues I don't think Switch is rugged enough to withstand the wrath of my 8 year old boy, especially in portable mode. I know for sure that my child will inevitably drop the Switch, and if the Joy-Con latches break without being dropped they surely would break from a dropped Switch also.
I am hoping Nintendo will release a Switch Lite or improves the build quality of this version, because until then the Switch is not leaving the house in my sons hands.
