I've tried the "Offline trade" two cups from other brands. A similarly large chamber cup whose lid does not shut properly and a very impractical tower. This Milk Powder Dispenser Avent is definitely the best. The lid and the closure of Portionieröffnung close really well. Granted, close by the firm, the lid rotates a little hard, but that is dearer to me than all of the powder in the diaper bag. Also the three-chamber insert is removable I find great. So you can use for the child the container later also for other things (apple pieces, etc.). So you have what it longer.
