I've had a sticker (bought on aliexpress so nothing of quality) on my deck for a bit more than a year and there seem to be no problems, regarding the carrying case I imagine stickers don't stick very much there but I've never tried

I don't think I could... I don't even totally want to put a skin on it lol.

But I like the photos everyone has shared! Please keep sharing :D

I went on a trip with some friends that also had decks so I put a sticker on mine to recognize it

It's been there since last november seems to hold up quite well. It's one of those made for electronics stickers

As long as you don't cover the vents, you should be fine

I've got several stickers on the back of my deck. The "I Voted" sticker has worn down pretty hard, but I suspect that the sticker quality on that one isn't so high. My other stickers are going strong, and the deck hasn't noticed any problems

I have the dbrand skins on both of my decks (a buddy from work sold me his 512 for cheap). That seem to be just fine for the wear/heat.

I also threw some vendor stickers on the dbrand carrying case, but just the hard plastic cover, so heat isn't really a concern.

This. Heck I have one of those vinyl skins on my Deck and it has cutouts for the vents. I have never had issues with overheating

I put an Apple sticker on mine. It’s held up well to humidity and heat. Don’t know about the case though

I almost thought you meant skins till I saw the other comment.
