[EX Q]: I read the book because it had good reviews but was not happy with. The main character in my opinion is too mean for a real woman. She did do alot to help her friend so that she could be with her boyfriend. But then turned and cheated on him with who ever happened to like her. I don't understand how anyone can think that cheating makes you want more. This is why we have marriage.
[EX A]: Good Review

[EX Q]: This is an excellent product. It replaces a unit that broke after some time. The old one had the battery door open and needed to be recharged. You need two AAA batteries. It's lightweight - good to travel with. Batteries can last 2-3 weeks between charging. All in all I'm very satisfied with performance - no complaints.
[EX A]: Good Review

[EX Q]: The ear loop fell apart.
