I bought this yesterday:
https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1
It smells absolutely rancid. I tried washing it several times with water and soap and it still has a very noticeable fishy smell. I'm trying baking soda right now. If that doesn't get rid of the smell, I'll try leaving it in a plastic bag with activated charcoal. If nothing works, I'll just throw it away. I have no idea why they let the covers leave the factory smelling like rotten fish.
Other than that, the case itself is bent and slightly loose on the right side.
