This Movek myMix monitor mixer is a great choice for personal use. Note that it doesn't come with a power supply, but it can be powered via PoE. There are a couple of known issues: the cover of the main knob is missing, yet the knob still works fine, and the screen has some scratches on it.

Using the Movek myMix Personal Audio Monitor Mixer is easy. First, since it doesn't have a power - supply included, you'll need to connect it to a PoE source to power it up. Once it's on, you can use the main knob (even though the cover is missing, it functions well) to adjust the audio settings as per your needs. When it comes to the screen, be careful as it already has scratches. Avoid using sharp objects on it to prevent further damage. For maintenance, keep it in a clean and dry place. Regularly check the connections to make sure everything is secure. If you notice any other issues, it's best to consult a professional.
