Mighty Boom Ball

Don't waste your money – Sound quality is what you'd expect, and it goes without saying that it also varies depending on what object you stick it to- although I use the term "stick" loosely. The biggest problem with this device is the adhesive pads. They're sticky enough to become completely coated with dust five seconds after being taken out of the box, but if you manage to get through an entire song without it falling off whatever surface you've stuck it to then you're luckier than I am. Utterly hopeless when stuck to a vertical surface- if the weight of the device doesn't unstick it then the vibrations sure will.

Might be fun as a novelty item for kids. See how many things they can stick it to before the pad (and it's two replacements) builds up with crud and no longer adheres to anything. At $30 RRP I'd recommend spending your money elsewhere. Portable Over-priced, terrible adhesive
