USB Rechargeable Portable MP3 Music Stereo Speaker with SD/USB Slot (3.5mm)

Pros: the led lights are amazing. really small and portable. guaranteed attention seeking. sounds good its size and price. cool design and again, with very nice led lights with constantly changing the color of the leds while playing songs.

Cons: has volume control but doesn't work, though you can just adjust it with your own mp3 player. cable came with it is faulty. buttons seem flimsy. made of cheap quality materials.

Other: good to buy if you plan to bring outdoor for pincic as it's cool and the sound it produced is decent but dont expect it to have very good bass. and loud for a 20dollars speakers. it's considered one of the best to have the disco lights.

Pros: It's very little , audio quality is excellent , great bass ! I have used with my iphone 3gs and no problems ! The light is very powerful , like disco ball...
It auto-detect the music when you plug usb key/sd card !
It also accept micro sd car with adaptor !
Very very good price.

Cons: It has some little cons :
_You can't charge for more than 3 hours (there is wrote in the box)
_You can't use it while charging (there is wrote in the box)
_Volume / Next track / Precedent track is weak !
_No remote control

Other: Fantastic ! Buy it !

Pros: Well built, sound is great and very loud for such a little device. the build quality is rather good, does not feel too cheap or plasticky. It will find pretty much any mp3 file anywhere on your sd card even if its not directly in the root directory. Still pretty amazed by the sound quality.

Cons: Uh... the charging of the device is rather weak, when i try to plug the charger intoo the device i have to play arround with the wire for it to actualy light up and start charging. Sucks that you supposedly can't or should not play songs while charging it, it says so on the box...

Other: Good purchase, my friend will love it.
