Used once at a party for over 8 hours. I don't know about the battery because I had it plugged in, but everything else was amazing. The sound at full volume is crystal clear, both with a USB stick and with mobile phones. 2 microphones with batteries and the whole time we used them they were stable, guaranteed. Simply awesome for its price.

AMAZING!!!!
Don't look elsewhere! With this money, you will buy a speaker that will be better than those expensive ones and YOU WON'T BELIEVE IT!!!
I listen to music at full volume and honestly I feel that I may have made the best purchase of the year.

The speaker is powerful, it doesn't distort, and overall I was very satisfied for a year. I used to charge it and then let it discharge completely before recharging it. Now it only works when it's plugged in. I have requested a return and am waiting for it to be approved.

UNBELIEVABLE PERFORMANCE - EASE OF USE - DOES NOT MUFFLE THE BASS!!!! SUPER powerful in volume (For school celebrations, having 2 microphones is a great convenience)

It has some connectivity issues. It takes a while to connect to my phone (iPhone 13) and requires some attempts to establish a connection.

It is a quite value for money product, its microphones are quite good with clear sound, in an open space it covers the acoustics well enough for entertainment without much distortion always considering the price. In combination with the price, the performance is very good, the battery lasts enough for a 5-hour full volume.

I bought it 20 days ago. And for now, as much as I tried it, it is satisfactory. How long it will last over time, of course, I cannot say anything. Just for its price, it satisfied me.

Today I received it, I've had it for 3 hours and it's been playing so far as I test it, very powerful, it's worth it for anyone interested so you don't have to search and get confused because there are so many on the market. For this price, you won't find anything this powerful, I say this because I've heard other machines but for anyone who wants, keep searching.
After 3 and a half years and with heavy use, it remains just as powerful, both its speaker and its battery

We have literally drunk the blood in the village, it has produced I don't know how many parties, clarinets, tables, it plays everything. Truly impeccable for its price.

I have bought 2 easily connected to each other, with Bluetooth for playback again the connection is funny and they play quite loud and clear. I have had them for about a year.
When the mobile is close, they make interference from 50 cm and above, nothing else.
I would buy them again 100%

I've had it for 2 days so I don't have an objective opinion yet, but I will come back to it. Initially, it has good and strong sound, a battery that lasts a long time, suitable for fun with friends and for parties. The microphones are nothing special, but with my professional-use one that I tried, there is a noticeable difference. I would like to know if its microphones can be replaced with others because it has built-in antennas and I don't know what the situation is there.

The speaker has paid for itself and continues to do so. The battery has slightly lost its duration.
