Kobo Clara covers

Just got a new Kobo Clara BW, and I was hoping someone could share what type of flip cover do you use?

I like the rakuten sleepcover but the exposed top and bottom edges make me anxious. I found another one that covers all four sides of the device completely (link below) but I do not like the quality at all.

I get that this is a choice I’m going to have to make for myself but I was hoping to get some opinions on whether the exposed top and bottom sides are really a risk in your experience.
