PADDY Vibe 305 Rechargeable 3W Bluetooth V2.0 Vibration Resonance Speaker - Black

Pros: It's just amazing what this gadget can do, I felt speechless when first seeing, it's loud, it's interesting and makes everybody around looks and try to understand how it works. Price isn't to far from the wired versions (cost is around 15~25 dollars) but the bluetooth makes all the difference, I just use the cable for charging nowadays. The mechanism is basic a half-speaker module with the magnet and a solenoid to transmit the sound through the ground

Cons: None

Other: ThalesFVB

Pros: Very nice sound on most songs, easy portable, easy connection with mobile via BT and cable. I was suprised and everybody around as well of nice sound that surface can create.

Cons: Surface shouldbe really smooth, otherwise it jumps, so not very good to use outside. Buttons seems easy breakable, but I hope it it won't happen.

Other: Very nice product for indoor use and to suprise friends what a small thing can do.

Pros: Pretty good sound quality, it's not hi-fi, but I was expecting much worse. Nice design looks cool inner battery bluetooth remote control over bluetooth back to your device (play,payuse, next, previous)

Cons: low frequencies are not so good, but still much better than most of laptops. bluetooth has a limited range it starts to interrupt in 3 meters or less if there are people between the devices It has a blue light in bottom + one of the button is dedicated to this ligh. The light canbe turned on even the device is turned off. But someone could take it as a pro.

Other: I would recoomend this to everybody. This is actually the coolest and best worked gadget I got from DX so far :)
