Title: Valves are super tough to remove for cleaning!
Review: Great bottles when used with nipples, terrible design with the sippy cup attachment. Valves are super tough to remove for cleaning, and they always are being cleaned. I recommend the First Years Clean & Simple, valve free! sippy cups. They don't offer them on Babies R Us online but the do have them in the store. They have them in 3 sizes , with handles and they don't leak! EVER! When making the purchase do it right the first time. Not like me 4 sets later :o(
