Bests & Worsts Reviews from Amazon

First off, I'll start by saying that I loved these at first. Although the button to push to get the drink out is tough for toddlers, these started out great. They are leak proof but they are impossible to get clean! If you plan on buying these to dispose after a few washes, you should be good however, these aren't something that you can continually use because they are impossible to get clean. They are literally mold collectors! The way these were made, make it impossible to get the lid clean. Do NOT buy!
