Title: CAUSES FUSSINESS & GAS
Review: This product makes a froth of air bubbles in the formula that won't go away on their own. Even after I swiped them away, my son--normally a good eater and quick to burp--was fussy and squirmy during the feeding and had difficulty burping afterward. Another thing I didn't like is that you have to hold the ON button down at all times in order for it to work... kind of a pain. Preparing bottles is a little faster, but what good is that if it makes baby unhappy? A battery powered powdered formula mixer seems like it would be such a convenience, but I recommend sticking to the old fashioned wire whisk.
