3 stars from me as it is not intended for the use I wanted. And because it doesn't have much difference from the cheaper rebeltec I had that broke. I mean in terms of volume. It doesn't seem particularly powerful to me.
In a closed space, it's decent. In the field where I use it, at a distance of 30 meters (without wind), it can barely be heard.
That's how the simplest rebeltec sounded too.
I basically got it for nothing because it is quite bulky and heavy. What can you do..
Apart from the volume being quite average, it has lights to create a nice atmosphere ????
The positive thing, though, is the sound quality. Even at maximum volume, it doesn't distort. Unlike the basic one.
It only picks up radio with the cable included in the package.
In general:
For its price, I don't think it's worth it.
Because for the same money, you can get a soundbar for inside the house and have LOUD sound throughout the entire house.
If you want to have a party in an outdoor space with this, it's okay for 5 people.
For more, you need more rebeltec.

Yes, it has good sound up to 70% of its volume.
Yes, the sound is powerful, balanced, and has satisfactory bass.
Yes, it is not too expensive.
However, its build quality is extremely poor. Very cheap plastic, very lightweight as a whole. In YouTube videos I have seen people who have opened it for repair because it has caused them problems, I have noticed that anything it has inside, such as cables, batteries, etc., is of extremely low quality, so you know it won't have a long lifespan.
It worked well for me for 4 days and then it simply started producing strong interference in all songs, as if the drum inside had been torn by one of the two woofers. I returned it and that was the end of it... If electronics merchants think that 75 euros is not much money and justifies devices being sold at such prices that are designed to last only a few months, then they probably need to come back to reality because that doesn't hold up.
You simply pay the amount and cross your fingers for it not to have a defect in the first week so you can return it, or for it to last more than 6 months so you don't waste 4 days' worth of wages on trash.

I use it for busking in combination with an iPad. It covers me more than enough. It would be more convenient if it had a strap to hang on the shoulder like the 460 for example, since it is very lightweight for its size

For the rebeltec, others have also said the same. Everyone should have one at home. This one is a bit bigger (than the already big 400/420) but it is a bit more powerful and has karaoke capability and sound adjustment with a wheel instead of buttons. What I wanted was a little more volume than the 400/420 for parties and it has it (we're talking about parties with 10-15 people, not parties with 50 people - for that, you need a suitcase).
For the money, it is the best with excellent bass and clear sound.
Its only drawback is the size (it doesn't bother me)

With one word, the tool is amazing!!!!!!! It offers much more than the 90 euros it is sold for! Hopefully, it will prove reliable in the long run! For now, it has been excellent for the past 2 months!!!!
