"I was really excited when I bought this so that I can cover the keyboard at the back when I use my Yoga 13 in tablet mode. Most of the time I use it in tablet mode. The worst part is that recently when I checked the yoga outer part is started getting some marks in the shape of the slot-in case. I tried to clean that up with clothes and some other cleaning liquids. But I was not successful.
Please avoid this unless you want to get some marks on your Yoga."
