Q: This book has some good basic information on the subject, but does not give enough depth or detail of each subject area to make it well worth buying. It's very basic, so I'm sorry I bought it. I'll go back and get something more detailed when I've had a chance to use this, as it's useless sitting around being passed from one person to another.

A: Bad review

Q: I bought it to my mom and she's been enjoying it. The battery last for couple of weeks, she has a very large area, but only 2 dogs so it's fine

A: Good Review

Q: You don't really get a sense of the main character's personality. Very easy read. Would have liked more substance to it. Overall very predictable ending but I like her style so give it a try. Not my favorite by far.
