I am an absolute fan Avent. However, I find it disappointing that this cap usually must be purchased separately! In other companies they are always part of a baby bottle. This should generally change Avent. The product itself is, for my understanding too expensive (after all, it's just about small plastic plates). I am disappointed by the quality. If one once it wrong, and turns the lock, she bent quickly. Moreover, I feel the ribbing to be extremely unfavorable since rapidly accumulate in tea and milk residues. This makes very clear the cleaning. What you also have to know that this cover must be inserted with the logo facing up and not like other companies with the bulge in the bottle. However, as regards the purpose of the cap, so they keep what they prom- ising it runs out of nothing, not even if you shake the bottle. Therefore, even 5 ***** for the intended use, but only a total of only 3 *** because of the listed defects by me.
