Wonderbag Slow Cooker = Hot Kayak Meals?

Amazon has this on their front page, and it looks pretty cool! Maybe if it goes on sale I'll give a shot   

and replace the yak-b-que-----blasphemy!

It's a $50 bag ...  my wifes already slow enough at cooking so waiting up to 12 hours for my meal is simply out of the question!
