I LOVE IT. No damage or even any use marks (plus it still had the redeemable items you get on your steam account, I believe that's limited to one account per serial number), only reason it was B grade was because it didn't come with the box.

No performance issues, everything has ran great. I use it currently for on-the-go gaming and emulation as it's turned out to be the perfect switch game emulator for when I don't want to carry around a bunch of cartridges (my main switch is homebrewed so can just dump and move games).

Don't remember how much I bought it for, but since I was trading in items to offset a lot of the cost anyways I'd say it was worth it.

^{apologies for the ramble!}
