Excellent product. This tiny speaker exceeded my expectations in every way. The first thing i noticed was how solid and heavy it feels. It's aluminum so it should withstand some heavy use yet it's almost small enough to use as a keychain. I got the second surprise when i put it on top of the box. I've never expected this much sound from this little speaker. It works with practically any box but after some experiments i noticed it sounds best with a smooth and thin but very rigid box. Smooth enough surface for the suction cups and surprisingly not an empty box but a small towel or piece of cloth made the sound less hollow and bass less "thumping".
I highly recommend both the speaker and the seller.
💯 💥 🤯

At first, I thought it was not very good, but when I put it on top or next to something like a completely empty container, the sound becomes much louder. I will use it well.

I thought it wouldn't work well and might break down, but after using it, I found the performance to be good and the battery life to be excellent. I intend to buy it again next time.

If you attach it to the glass case, it sounds great.

I recommend it 100%, the sound is amazing, it works better on materials like cardboard, thin wood, plastic, but the sound quality is very good, and it's not very big, it's the size of an AirPods case.

The quality of speaker for that price and the resonance and material was an expert choice as it felt premium.

Excellent product, the mini speaker was smaller than I thought and the sound is enough to accompany you in a studio or bedroom, the best! It's great as a gift, connects via Bluetooth and the battery lasts a long time, recommended!!

Quality looking speakers made with solid feel and lookin materials, the sound is great once you find the correct object to place them on so you have to experiment before finalizing your placement. Connectivity was quickly paired between the two speakers i purchased and connection to the phone was instant... I would purchase these again if needed 👍 👍

Very great speakers! People said dual pair doesn’t work but it does for me! !

the sound is good, not very loud, only 5 W. But on the surface of plastic or wood, there are nice basses. I recommend it because the speaker fits in your hand, and the sound is like from an expensive speaker.

This baby is absolutely worth its money. That's exactly how much it should cost. Because with such a small size, it produces sound similar to the speakers on a television, maybe quieter. It all depends on the surface.
But what a flight of fantasy for pranks, because there is sound, and it's difficult to determine exactly where it's coming from. 10/10

Great sound for such a small speaker. My boy loves it.

I tried it and it wasn't charged yet, I placed it on different surfaces like a table and it sounded a little louder on the window glass. But what surprised me was that when I put it on the box it came in, incredibly the little box turned into a speaker. Then I tried it on the shoe box and the volume increased even more. For now, I'm charging it and I really like it.

It works perfectly and the four suction cups ensure a good grip on surfaces. Obviously, the sound quality is not comparable to a Bluetooth speaker, but still the volume is high and it sounds good. Important not to use surfaces that vibrate.
