I have used Playtex nursers with drop ins with all 3 of my children! The third uses them right at this time! And for 11 years they have been a timeless addition! I can always depend on them to be easy affordable as well as dependable! They have never ripped on me, they have also been easy to clean! All though the designs have changed the awesome quality has never changed! ( I must admit i sometimes use the classic ones) My babies have all stayed on the nurser aslong as they were on a bottle and have refused any other kind of bottle when it was offered to them! Playtex has been helping me raise healthy children since 2004!!
