Amazon Protective Cover for Kindle (7th Generation, 2015), Black - will not fit 8th Generation or previous generation Kindle devices or Kindle Paperwhite

i love this cover it's pretty and pink and does the trick i like that it easily folds back all the way and doesn't get in the way of reading has held up well for me i've had it about six eight months i think i had ordered the wrong size case i returned it got my account credited and ordered the correct one it came today and i love it no hassles no delays i am happy i got this case today and it fits my 7th gen kimball very well although it doesn't cover the entire edge of my kindle touch more like three stroke four but it is holding it securely i'm confused on how the cover turns the screen on or off when i open it i see the add screen saver of my kindle and it doesn't appear to turn off do i need to change a setting within the kindle i look forward to this case being the little black dress for my kindle fitting all occasions endurance and usability i like that the case is relatively lig
