Amazon Kindle Kindle 8th Gen 6.0000 WiFi E-reader

i used to really like back market and told everyone about them. Sadly the last two products I got have been horrible. This one cannot access the libby app to read library books even though all kindles should. It ran out of battery and won't recharge even after being plugged in all night. Very frustrated. I used to save money with back market. Now I am def losing money and will need to shop elsewhere after years. The company got cheap. The other product I bought was a "excellent" iPhone 11 pro. It overheats constantly including when I first got it. It shuts off randomly. It stops during live videos and facetime calls. So many issues. I cant keep it in a case or it overheats right away which makes it vulnerable to breaking. Should NOT have spent the money...ugh.
