One of the evaluation questions here is whether it has good sound, which is irrelevant since it is determined by the speakers. Apart from that, it does its job at the expected level, but I want to draw the attention of those who want to buy it, that the package DOES NOT include power supply, only the amplifier, which needs a converter to work properly at 12V-5A. Of course, because I didn't have a 5A converter, it worked with the one I had at 2A (thankfully I had that one), but it is not recommended, of course.

Something else that might annoy some people is that every time you change the source, for example from Bluetooth to aux, it has a recorded message playing as a notification, and you might be startled the first time you don't expect it, since it doesn't mention it anywhere. It is a decent device for its price since obviously... it is not intended for high-powered speakers or a club!! I use it with 2x10w speakers and I imagine it won't be a problem even with 20-30w. Fortunately, bass and treble can be adjusted.

It is fine for its price. Be careful because it requires a transformer. It also has a radio and Bluetooth and they work very well

It does the job and the Bluetooth works perfectly fine. For its price, it is very decent
