This book was a complete waste of time and money. It does not teach anything. Just lists the different ways to cook each dish. If you want a great cookbook, get Rachael Ray's- she is hilarious. My only advice would be if you are going off the grid this will give you some inspiration, but for everyday cooking it's useless. A lot of recipes have more than 1 ingredient listed. Which I found odd. I've never used most of those ingredients in one recipe. Do not buy.

I've been in an office environment with this product for a week, and am looking to see how long the tip will last before failing. The rubber is starting to pull away, showing some signs now of cracking, I only use the tool occasionally but it should not be failing so soon. Too bad cause it's perfect ergonomically otherwise. A very high defect rate on mine makes me think that's just the nature of the beast. Would love if they could re-design it.

This was cheap crap and only lasted about two weeks. Not very happy at all.
