I agree as well, my grandbaby is 7 months old and my daughter and I had done a lot of research on different bottles before Katelyn was born. We heard negative reviews because some mother's thought the bottles had too many parts to them. These women are nuts ...... you pop the beige cap onto the straw which then goes into the bottle - you attach the nipple to the cap - then screw the cap to the bottle. Wow - how complicated was that? Guess they rather have a screaming baby with gas pains then use this great bottle. We sure have a very happy 7 month old who loves her bottles.
