I'm happy with my portable dock I got on eBay a couple of months ago.Grant it I had to put it together myself but it was easy.Ive had no over heating issues and my fits really good in my case
I think some of the concern stemmed from people reporting that their screens were being scratched from the dock itself that was supplied by Nintendo at launch. I know personally we got those little third party dock slips (made of fabric) to help buffer our Switches when docked.
I don't mind the official dock for at home. But it would be nice to have a smaller one for going to friends houses an playing on there tv.
Tried 4 person on switch itself. Not good at all xD...
Want a portable dock that will fit in my bag better
