Cheesy re-use of public-domain first edition of 1918 dressed up as a new edition. Get the real one by Strunk and White.

What can I say about the 571B Banana Slicer that hasn't already been said about the wheel, penicillin, or the iPhone.... this is one of the greatest inventions of all time. My husband and I would argue constantly over who had to cut the day's banana slices. It's one of those chores NO ONE wants to do! You know, the old "I spent the entire day rearing OUR children, maybe YOU can pitch in a little and cut these bananas?" and of course, "You think I have the energy to slave over your damn bananas? I worked a 12 hour shift just to come home to THIS?!" These are the things that can destroy an entire relationship. It got to the point where our children could sense the tension. The minute I heard our 6-year-old girl in her bedroom, re-enacting our daily banana fight with her Barbie dolls, I knew we had to make a change. That's when I found the 571B Banana Slicer. Our marriage has never been healthier, AND we've even incorporated it into our lovemaking. THANKS 571B BANANA SLICER!

My blow dryer is a standard size. Waste of money.

I think it's an accurate assumption that we parents are typically the buyers of these kinds of books, and that when we hand our kids the telephone book sized prep books we've purchased the kids are hardly pleased. What a surprise it was when this book came to my house. Don't get me wrong, this is not a small book, but it has a more manageable feel and it didn't cause my son to run screaming from the room. That's already a good start from my perspective. That said, the proof is in the pudding.

Most folks are only taking into consideration the marginal cost of the CO2. We must also consider the capital cost of the device itself, and how much its used. Given the warranty is two years, depreciate the machine cost over the amount of water you drink over that period along with the extra bottles and CO2 exchange canisters. Also, one CO2 canister does in fact get close to 60L of soda (if you stop filling after the first air burp). Here is my calc:
