A follow up to my last post about the water bottle thing. Having used for a while now I am even more convinced that it is not worth it. At first I thought it would be cool to "pour" the items from the spout of the water bottle, but that is not the case. The bag I closed was a bag of mini chocolate chips and they were just too big to pour. so you had to remove the water bottle top, pour out the chips and then return the top. Also I found as I used it that it was best to trim the top, if there was too much excess "bag" it didn't close or fold over right.
