We bought two sets of 2 liter Rubbermaid containers to fit in the fridge door. Both sets leaked at the top when you poured them. I bought this Sterilite kit. They don't flow at all. I put packets of Crystal Light in, fill the jars, then turn them upside down a few times to shake them. They don't spill when I turn them upside down and they don't spill when you pour them. They are easy to use. I like that they have a pen. My son can easily water from it.
