Okay, it works for its price, good. The battery, however, lasts only 1 and a half hours and it doesn't reach more than 4 meters, it doesn't reach through walls for me. I used a USB but the buttons came off. Buttons and holes with connections have the same cover. Finally, I ordered gray due to work so it wouldn't get dusty, but I received black, what can we do, it doesn't matter. Very good price. I would buy it again

It is a good product. I connect it to my Android smartphone via Bluetooth and let me reveal a magic trick on how to make it produce louder sound. Simply install the "SpeakerBoost" app on your smartphone and increase the volume by over 100%. Another trick to prevent the battery from draining quickly is to place the smartphone close to the speaker.
