For the price it's decent (at least after replacing the internal micro sd card with a better one.
The one BIG issue I've had is, if you need to connect to Bluetooth to anything that requires a passcode (like my car stereo), there's no on screen keyboard that pops up and I can't get a Bluetooth keyboard to connect to it. Some AirPod models (including the one I have) apparently also have connection issues.
Also, there's no real way to create playlists other than manually creating folders on a computer and copying it over that way.
Overall the form factor is a nice iPod type experience, but the software is a bit too much like an early 2000's cheap mp3 player. You can flash Rockbox on it, which gives it a bit more functionality, though doesn't fix any of the issues I listed above.
