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.

Although I don't know about durability, I am satisfied with its value for money. It won't blast your ears with the volume, but it is satisfactory.

What is not mentioned is that it has True Wireless Stereo (TWS), meaning you can connect a second speaker that will play exactly the same.

Also, its Bluetooth reaches at least 6m, which I tested with walls in between, without any problem.

Two negatives:
1. The volume buttons have other functions, so if you want to increase or decrease the volume, you have to press and hold, while pressing once changes the song for example. This way, you can't always achieve the desired volume, but you might change the song.
2. There is a static sound in the Bluetooth. You won't hear it at normal volume, but when it is very low, you can hear it.

The battery is around 300mAh, if it fits your hand and you're dealing with it, it can hold a 18650 battery that will significantly increase the duration
