Review on Contigo Autoseal Trekker Kids Water Bottle, 2-Pack: Granny Smith & Nautical - Perfect Hydration for Active Kids! by Gus Pierson

First of all I would like to say that at first I liked it. Although toddlers find it difficult to press the button to get the drink, they got off to a great start. They are airtight but impossible to clean! If you plan on buying them to throw away after a few washes you should be fine, but they're not something you can use all the time as they're impossible to clean. They are literally mold collectors! The way they were made makes it impossible to clean the lid. Do not buy!
