Surpringly powerful, sound quality is good, holds a charge for quite awhile

Works very well but does not get that loud great battery life, size and Bluetooth connection

Coolest little gadget to have at a party! The bigger the box, the bigger the sound. Thanks to my sister showing off hers had to have one too

Good bluetooth IC, terrible otherwise. Tiny batteries. Speakers buzz and cases vibrate (not when they're supposed to). Suction cups are worthless. Sounds like severe voice coil rub. Good concept, poor execution. Unusable, don't buy. Go buy a quality mono version for the money instead.

These things are tiny, I am amazed that they were able to incorporate a battery, bluetooth + amp + resonator in such a small configuration. Bluetooth connects easily, in dual speaker mode it connects without issue, sound is not as loud as you would expect, but amazed by the sound these small units produce. The pre-mounted sticky pads sticks to all surfaces tested (melanine, stainless steel, boxes, tiles, mirrors, wood, glass, plastic, etc) which is a plus, I did not need to use the suction cup foot. I have tested the product on many different surfaces, firm boxes seems to perform the best, sound is dependent on the surface, Shower doors reproduces clear sound but edging towards harsh treble, not so much bass. Boxes has more mid frequency response and lower treble. Its a nice gimmick to show friends but I wouldn't use it for daily audio, therefore I agree with the other product reviewer, you might be better off with a portable bluetooth speaker.

Was ok

Didnt work well, not loud at all. Stopped working after 2 uses.

Learned about this speaker concept over 20 years ago and was the first thing I thought of when I needed some music for my rides. Bluetooth Kits for your helmet cost $300 or more. Glad a company was able to make it wireless. This device vibrates and essentially shakes the surface you put it on and turns it into a speaker. Obviously you cant put it on a brick or a glass of water and expect amazing sound. Something thin and pliable will work wonders for you.
