Last week I went to the local Apple Store to inquire about trading in my iPad Mini 2 for an iPad Mini 4 with more storage. My 2 was in perfect condition (less than a year old) and I had a leather case from Apple ($79.00) on it. I asked the sales person if it would fit the 4 and I was assured it would. My mistake was not to have him try it in the store as I chose to set it up at home. It did not fit. As they had already recycled the Mini 2, I was out the $79 for the cover as it was now useless.
If you have accessories that you want to reuse, always try first in the store.
