Got 2 bottles, one to test it out, and the other to use when I needed it. The test was done with strips, and it failed multiple times. I followed the instructions to the T. Ended up returning the other bottle. DO NOT listen to the people who say it works, it doesn't work whatsoever.

Who hasn't had a bad workplace experience? Crazy colleagues? Wack-a-doddle bosses? If you've ever worked, this book is for you. You'll never guess the ending! Great book!
