These pacifiers are great: 1. Babies can not get hurt by the soft material. 2. The nipple fits always! There is no up and DOWN which is particularly useful at night. 3. There is no dirt-prone (seam) points, as the material of a piece is. 4. The suction widens at the end. So the pacifier can be drawn in the usual way, similar to suck the breast. (Many babies are of tapering suction parts which pass abruptly at the end, confused. The nipple sits not so on a board.) 5. The uniform round shape of the suction closest resemblance to the nipple in the baby's mouth. All flattened and cherry shaped teat make up my mind makes no sense. A nipple confusion we had in any case with this pacifier not (the other copies but were also not even accepted).
Only to improve would be the mounting option. The handle portion of the pacifier might for example include a larger hole or a recess for a Schnullerkette.
