My son takes only MAM soothers and I'm really happy with the silicone suckers! the symmetrical shape of nipples and pacifiers shield is great, thus he is never upside down in the mouth! Although would have liked the design pictured get the robot, but that does not change the good quality! they are really sturdy and do anything to come to clean in the dishwasher and are (only) replaced after 5-6 months. really can only be recommended!
