I would only get this if you are a tinkerer.
Not a bad module, considering there are no real alternatives. It just has a very steep learning curve which took me weeks to get to know in the software library created for it in Arduino. It seems temperamental at times, and will not always work until you change your code around in a certain order, and put delays in so that tracks can play correctly. For instance, I could not get volume to do anything if I coded it before changing the EQ.
Sound quality is quite good once you put a ground loop noise isolator on it (which costs about twice the price of the player), otherwise it is pretty bad if sharing the same power supply. Lots of noise in the headphones, which a cheap in-line isolator fixes.
De-soldering the pins to hard wire in is a nightmare, since it is so small and delicate. I bricked one and had to buy another, waiting over a week for it to come. The functionality of the SD card took me serious experimentation to get right, after researching file structures etc and how to format, and it can be a little slow, but this might be the Arduino library not being optimized.
The graphic EQ is nice on Rock or POP, but I wish you had more control.
All in all, it does the job, but only after so much time has been spent on it, and so many YouTube conversations, that you wonder if it was worth the effort. That said, my project was complicated and I am a stickler for perfection.
