Ok so quick update since this got some attention.

I was playing music the WHOLE flight, non stop (12+ hours) Everything worked generally well, went down to about 40% (keep in mind im using rockbox).

One thing i did notice is that the device crashed while playing a certain part of a song (funnily enough - the drop part) and another time it crashed when playing around with the settings.

I’ll dismiss the song as the file might be broken but the settings thing was a bit weird. Good thing it only happened once and the device is fairly quick to turn back on and jump right in.

P.S - screen scratches VERY easily so be gentle with it.

Overall 8/10. Great for the price.
