It does exactly what it says! Very honest... Its size doesn't impress you since it fits in your palm! Amazing, I initially connected it with a small power supply I had available, only 13.5 volts at 1800 mAh to test it and it already plays amazingly. It drives old branded 6.5" speakers (Ideally it needs 12V to 24V 5A for better and stronger bass). I will come back when I connect a new power supply... update 14/5 new 12v 5A power supply from an old LED strip! Deeper bass, no distortion, zero noise! Excellent... I can't believe my ears!

It comes in pieces, it also includes a small screwdriver to screw in some small screws. I expected it to be a bit bigger, to tell you the truth, it's 5 * 5 and three centimeters high. It's incredibly reliable, the app is a bit of a hassle to set up, but once you configure it a little, you don't use it again. From there on, it depends on the quality of the speaker you use. For its price, I think it's perfect. It came without user and assembly instructions. The app is called Sinilink.

Update: I connected regular 300w speakers and also downloaded a free equalizer, DeskFx by NCH Software, where you can adjust treble and bass, and it's awesome.

One detail, it doesn't have a power supply and I used one from my previous router. It needs 12 to 24 volts, the more volts, the better the sound, up to 60w

It does what it says. It also has an app to control some things like source switching, volume, and 5 preset EQs that unfortunately we can't customize. For its price, it gets 20 out of 10!

Well guys, I have made a great system with two speakers from my father's old system. It doesn't cut out, DOES NOT GET HOT, and the quality for 11 euros is similar to a small JBL speaker I had that cost quite a bit more.
