PROBLEM: This was really not worth my time and money. It made for a good coaster though! I wouldn't waste your time. Just wasn't what I'd expect from such an acclaimed author.

SOLUTION: Bad review

PROBLEM: I had some trouble figuring out where to find the batteries that came with it, so if you don't have a screwdriver (comes in small package of 4), think twice first about using it and ordering it right when you're leaving for vacation. You will need it at your vacation home.

SOLUTION: Good Review

PROBLEM: I wanted some kind of light and portable speaker for my iphone to use in the shower. This seems perfect, but it does not work. The unit lights up, plays music, etc. But there is no suction or pressure on either unit, so water simply drains out as soon as air bubbles get into it. If you put a small bubble under it, then push any part of your finger gently against a portion of these tiny bubbles, you'll hear nothing. Really disappointed. Would have been really useful if only one worked.

SOLUTION:
Bad review
