[EX Q]: We never received this item. It was shipped one way, then sent via carrier pigeon. Very disappointed! Did not bother returning.
[EX A]: Bad review

[EX Q]: The product works, but at no level is it particularly good to have or extremely bad as many other reviewers seem to be saying. It does look great, and feels nice, the material seems very sturdy, and even with a full charge, has sufficient battery life to last for hours of usage. BUT.
[EX A]: Bad review

[EX Q]: The idea of a book about how to change your habits is an appealing one. However, because people don't tend to implement the ideas in this book immediately, I guess that they didn't do it before reading it, because their lifestyle hasn't changed. Some might argue that's good, but when it's been years and you've still have the same habits, you really can't get something out of this.
[EX A]:
Bad review
