The mystery box is great for when you can't choose what case you want and the great cases make it just soo to make it worth the wait.
The assessor's were terrible. Description said could be a wireless charger or left charging cable, I got a magnet, a cheap badge that has 0 to do with the theme they said it would be, then received to very cheap and tacky keyrings that were the same. Was very disappointed.
Led case didn't work well and did not cover the case, but have been sent a replacement.
The 2 surprise cases were my thing but I appreciate its a mystery.
Personally I wouldn't bother with the mystery box. I would have felt less cheated if I got at least one good or premium accessory and not just cheap rubbish they don't even sell on their site.
Wasn't the case I selected and one of my glow cases don't work
