As far as durability goes, I've had this case for a few months and haven't had any problems with the corners chipping or break off, or the cover causing any issues. I use my Kindle nightly to read before bed, and will also throw it in my messenger bag every morning in the rare chance that I might have 10-15 min of downtime during the day where I can pull out my Kindle and squeeze in a chapter. The magnetic closure with the on/off works fine, and it fits the Kindle like a glove (as it should). I've been wary that there could be quality control issues with things breaking off since there's so many reviews of that happening, but so far I would have to say that my cover is doing well. I'm not the most careful person either and I'm not babying the case, so it's being exposed to what I would say is the standard amount of abuse a case should be expected to handle, and so far so good.
