Example Input: This is my 4th Six Sisters Stuff cookbook and this one is easily my least favorite. The recipes seem so heavy - lots of frying, lots of high calorie/fat ingredients (cheese, pasta, cream). Actually, I love the dessert section in this book but probably for the same reason why I don't like the main dishes section (high caloric, high fat = yum!) My favorite of their cookbooks that I go back to lots is their "A Year With SSS".
Example Output: 3

Example Input: Purchased for my husband who has issues with walking. Works great, but a little too slow for me. His doctor said this was a great idea to build up leg muscles.

Example Input: My husband bought this for my Birthday the end of January. By mid-March we had already had one light go out. The lights are hard to position over multiple plants or seedling.
