I'm debating which ultra-thin case I will get for my iPhone 7 Mat Black. Both the Peel and the Shumuri look very interesting. Does anyone have any experience with these ultra-thin cases? I want the most transparant one. Shumuri is advertising there Slim Extra as a Clear model and Peel is naming theirs Black. I just want to see the Apple logo and imprints on the back through the case. Which one to choose?
