Bests & Worsts Reviews from Amazon

My husband and I purchased these cups for our daughter after reading great reviews about them. But I don't get it. It never seemed like my kid was getting anything out of the cup, and I even tried drinking from them and couldn't get anything out. ?? We just switched to straw cups. I did keep the bottoms of these cups and we now use them as regular kid-sized cups for my daughter to drink out of. A friend of mine also had the same poor experience with these cups.
