😐Previous Rating - 🌸 I don't like writing bad reviews. However, it is worth writing about it. I have not received any compensation for this honest review. I had many MP3 players. Not only is this MP3 player complicated, it needs to have a case. It's like holding ice cream in your hand! I'm not kidding, keep cool! And the controls are really hard. So if you're looking for a basic MP3 player, this isn't it. Pity! 🌸March 2021 Update🌸2021 Update - My updated review (the main answer to the question) is also in the Questions and Answers section. I thought I'll write the answer here to help others.🎶🎶 This mp3 player does not allow you to erase the device. You can use almost any device to clean your SD card. Also on a Fire tablet. After erasing, play music from your Fire tablet, computer, friend or whatever in the SD card and don't take it out. Important. So make sure you have the music you want. Organizing is something else entirely. If you play around with it for a while, things get a lot easier. It feels very cold. So if you're sensitive to such things, I'll keep that in mind. So basically you can put an SD card in the slot, but you can't use the device to erase. Personally, I am not satisfied with this player. Everything seems to get complicated and it's really hard to see. Did I mention that it is very cold to keep? I think I'll stop at the rating. Maybe this helps. Hope this helps. -smileThanks Revain.com 🌸
