Long story short - these are very tasty. We have purchased a number of flavors from this brand, this is my favorite.  BUT... as noted by another reviewer - these contain MSG in the form of "Yeast Extract".  It has become a popular means of hiding MSG lately by calling it different things, as a person who now finds himself having to use more caution in what I consume I find the whole process of hiding in plain site very bothersome.  Also, the bag is not very large, but half of it is air. This may well help in shipping, but when paying a premium price for 'organic' it just seems more deceptive.

Save your money and do not buy this product. Does not even come close to bacon flavor more like a hickory smoke taste. After everyone in my family tried it we all agreed it was nasty(we're not picky either).

The lid merely sits on the top, and is a huge pain to get on and off, especially since we use this to freeze milk. Half the time it spills everywhere while I'm moving it to the freezer. Sooo annoying but at least the bottom is silicon. It will be useful for baby food and less-liquid things.
