ok it was time for mp3 upgrade. My mp3 compared to this are dinosaurs, that’s how old they are. I had a little prob w sync but it was cause windows need it to update. After that it sync fine. I also had a prob where it wants to record all the time but that’s user error cause I am used to old mp3 and not new tech. This mp3 has 3 ways to output audio. I can use my headphones for private hearing or the little speaker when I am lazy to use Bluetooth or headphones. The sound tru the little speaker is not that loud but is perfect for when I need to hear a song. The video was wonderful no problems there but I prefer to see my videos in bigger screen. I really need it this to save my old songs that I still have on my CDs that are soon breaking apart. So the memory slot to add more memory is needy so thanks for that too. The ebook is good but if the book is more than 20 pages then is too small to keep turning and turning pages, the battery last a long time. I charged it first day and after many uses I still have more than 1/2 battery left and I did use it a lot on first day saving my le cds into mp3. The only prob is I keep making recordings no idea why is soo sensitive but is prob cause my mp3 is more than 10 years old so I have to get used to new technology. Same happens to me with other devices people tell me I press too hard..lol..they right.. thanks for this device now I can save my old MUsic cds and I have 3 ways to output audio. I have a ebook reader. Video player. And the bonus is I can integrate this device wil all my Bluetooth devices and yes I have a ton and it works so far with most of them I have tested..the step thing is no for me cause I use a bracelet for that . Radio works fine too but I am no a radio fan.
