[Q]: Bought this for my 5 year old Justice Leaguer. My son is not a rough player but we went through 4 (YES, FOUR) of them before we finally got one where the elevator didn't break in the 1st 2 weeks. Mattel needs to get their act together and design toys that have durability. VERY disappointing!
[A]: Negative

[Q]: I'm sure these are great socks, but I was slightly disappointed when I thought I was getting 3 pairs for the price listed...my package arrived and there was only one pair for the stated price. I feel like the image with 3 socks was deceptive and "false advertising", as it states nowhere else how many pairs are sold for the stated price. Hope I enjoy the socks, but thought I'd warn everyone else before they buy these and expect more than what you'll receive.
[A]: Negative

[Q]: There are serious inaccuracies in this book that can cause a great deal of stress for a celiac. The section on medications with gluten is especially troubling as it causes someone who thought they were safe to worry for no reason. Most troubling is her treatment of the risks of cancer. Her treatment is both superficial, incaccurate and unrealistic. First she says that the risk is the same whether you maintain a gluten free diet or not. Then she says that the only thing you can do about it is to not worry about it. Her discussion of picking food out of a sandwiches is poor advice. In one section she understands the problems of cross contamination, yet doesn't seem to understand that picking apart food is more of a risk than using a toaster. Finally, her flip advice about how to avoid answering questions is ridiculous. Why not be honest instead of avoiding the questions. It's up to the person as to how many details they want to give. But avoiding the issue is not the answer.

Negative
