Product review (5 stars): Rubbermaid Bottles
My whole family loves these bottles. They are so well made!  We fill almost to top with filtered water & keep in freezer. Then when ready to drink, flip lid up & fill to top with more filtered water.. They come in larger size ,too, so whatever you prefer.
They are spill-proof & just the BEST !!! Fit in auto drink holder & also I take to work with me every day so no spills around desk/computer area... Buy them "please", so they never stop making or selling them.. I keep 4-5 new spares in pantry 'JUST IN CASE".I give them 5 stars cuz they are that good! P.S. Don't buy the ones with straws built in , not so good at all..
