Its rubbish! The O/S only boots about 1 in 3 times.
When it does boot the s/w see's tracks multiple times. I cut down to only having a single album in my music library and the problems persist. I have tried different SD cards etc.
The 3D print files are also poor. The orientation is crazy! .... and the buttons do not fit. I have resized them and messed around but the end result is poor. Would persist or even contemplate designing my own case for it but there's no point until the O/S boots consistently and the s/w problems are fixed.
