The Munchkin formula dispenser has made travel so easy. I first bought one of these since my daughter was always in the car going places and we were away from home a lot. It saved a lot of space versus having to lug around the huge cans of formula we bought. It was perfect for short trips or even over night stays. It never leaked powder and was pretty simple to clean. I purchased another brand of formula dispenser but stopped using that one because I could never get the lid off to clean or fill ot but with the Munchkin one I never had any problems. I had 3 of these all together and as she got older one was used for toddler powder formula on trips and the other two for various snacks on the go. Everytime I see a family memeber carrying around bags of baby or toddler snacks or cans of formula on short trips, I tell them about these. It helps that they're relatively cheap and seem pretty durable. The three I have, I have been using for close to two years now with now problems.
