I got an Mcover for mine. Only had it a couple of days, but I do love it! It's not elastic in the corner, but shaped leather corners. Don't know how these will do after a number of in/out of the reader, but the case seems very well made to me. I like the rubberband closing. Prefer it to all the magnetic ones you usually see on the cheap covers.
