Title: It doesn't work in any of the bottles we have
Review: I thought this was a great idea - so I bought 2 sizes. However - it doesn't fit in any of the bottles we use. It rests on the bottle top and doesn't allow the cap to screw on. I tried on both Evenflo Purely Comfi bottles and Dr. Brown's. What a waste of money . . . it should tell you what bottles it will work with so you don't waste your money.
