The media could not be loaded.  a little finicky with input voltage, id recommend an inline volume control to separately control the input to the unit if your gonna use an input source rather than the mic input. other than that, im happy with it. usb c power unlike the described photo, and a rocker switch/push switch to control everything rather than 2 buttons, must be an updated version. has pots on the back to adjust brighness and left and right channel if you want to run it in stereo mode (im running mono) its very similar display to the kenwood graphic eq i had that i was trying to replicate. i didnt use the case it came with, i mounted it inside my computer, looks pretty sweet, came with a purple plastic sheet which mellows out the color, not sure if it was a protective something but i put it over the display and like the shade

The frequency bands don’t seem to cover much of the spectrum. In addition, I’m pretty sure that low frequencies are displayed rightmost. The always-on AGC makes any kind of level assessment meaningless.
