CHACHA Portable Wireless Resonance Vibration Bluetooth Speaker System speakerphone + SD card/ Party lights for iphones, any smartphones, tablets, and computers (BLACK-CHACHA)

sound not nearly as good at filling the room as the Mighty Dwarf--seems like they are trying to capitalize on the Mighty Dwarf's ability to turn tables and any surface into a speaker by vibrating---cuz they put the word "vibration' in their title--but the vibration does not seem to add appreciably to the sound quality.

Not a true conducting transducer speaker. This speaker has a moving cone to deliver sound to a surface It is not a conducting transducer speaker which has metal rod is wrapped with the voice coil to transmit sound into a surface. Before making my purchase it would have been nice to have the description give this information.

I have tried to contact the company over email and have not gotten a response. The website also does not offer a customer service phone number. The volume button broke after less than a week of using the speaker on vacation. The button is stuck in and will not come out.

This is not a true vibration resonance speaker at all!! It is a regular speaker, it's a decent speaker but not what was advertised.

excellent

Exceeded expectations for it's price.

We love it
