[Q]: This should be more than an $18 speaker system. You will waste time and money.
[A]: Bad review


[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]: It's very well constructed, especially considering how low price. If you need a case with all your phone needs, this really fits the bill. You should get one ASAP! Good product! :) Fast shipment! Highly recommend to other buyers! :)
[A]:
