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

[EX Q]: Poor quality! Plastic frames broke upon putting on these glasses. One fell off and then broke. Not worth even the price. Returned this item... too bad, because the glasses looked great!!
[EX A]: Bad review

[EX Q]: I found this book to very informative and helped me with many things as a new mother. It was helpful in helping me determine what issues my child may have that are common or not so common. The other thing is it gave you tips on how to deal the issue of your child having ADHD. My son has ADHD but he hasn't been diagnosed by doctors, just parents who don't believe it. It's ok when kids play pranks like that, it's great for the parent.
[EX A]:
Good Review
