[EX Q]: The zipper didn't work at all. And it felt like the zipper was covered in wax or something so my hands were nasty after spending 15 minutes trying to get it to work.
[EX A]: Negative Review

[EX Q]: It really sucks I plug it in and it says charging then back to please connect a charger! It takes more power then gives!
[EX A]: Negative Review

[EX Q]: I absolutely love the book cover --- it feels good and solid in my hands, has padded protection for the kindle screen, AND, best of all, it locks into place on the left edge instead of being held in by corner straps. Looks classy, too!
[EX A]:
Positive Review
