These covers are fine I guess, but they make the Nook heavier and bulkier and that is not the idea of an ereader in the first place, in my opinion. I prefer something like a case I can store it safely in and take out when I am reading and hold the Nook itself. I purchased a simple sleeve for $7.95 including shipping at
http://nuvo-tek.com and I am very happy with it. Besides the very low price, it fits the Nook just right.
Just my two cents worth.
