I have one of these and a dumper.

I took all of the games we have and dumped them onto an SD card. I use it for the second switch we have that our kid uses.

No messing about with swapping cartridges and taking a chance on losing one, which has already happened once.

I ended up with a V2 which is even better. No wear and tear from popping the cartridge in and out and all the games on it.

Aside from the “inconvenience” of having to push the button to roll through the games, it was worth it.
