[Q]: This was my first attempt at a diet or exercise book. I bought it in paperback for the price of only $3.99 and thought I'd give it a try. The format itself is easy to follow, though there isn't enough detail on each recipe -- if you don't know where to start, as I didn't, it's pretty difficult getting back around to it. The actual recipes themselves are not that exciting. I've made them several times since receiving it; they taste alright, but nothing too special.
[A]: Good Review


[Q]: This movie was just plain awful. I found it boring and the acting not very good, in my opinion. Do not waste your time on this one.
[A]: Bad review


[Q]: 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.
