Negative Positive
Title: infuriating!!
Review: The good points... easy to clean, no stupid liners to deal with, clearly marked nipples, correct measurement marks on bottle sides(surprisingly uncommon)The bad... impossible to tell if the collar is screwed on correctly, until you shake it and milk gets everywhere, or dumps all over baby during feeding. Also slowest nipple is much faster than playtex or gerber, and tough for slow eaters to get used to.The screw issue makes these useless for me to travel with, as everything gets soaked. Just a stupid design.
Is the review positive or negative?
