Maymom Dome Caps, Screw Rings, Sealing Discs Compatible with Avent Natural Bottles, Avent PP Bottles or Natural; No Nipple Included. Convert Avent Classic Bottle Into Natural

We have bought these as the reviews are mostly positive, but were very negatively surprised by the manufacturing quality. One of the rings is totally useless, does not hold on the bottles at all, others seemingly fit, but do not let air when combined with original Avent teats. The only use we have out of them is to use 3 of them with their sealing washers to store milk in the fridge and we need to be careful not to mix them in with others.The manufacturer needs to get their quality control sorted.

Ein 2er Set hätte mir auch geholfen/gereicht, gab's aber nicht. Dennoch sehr hilfreich, praktisch und passend zur bereits vorhandenen Avent Serie.

Habe sie anhand diverser Rezensionen gekauft da es für Philips Avent Fläschchen keine originalen mehr gibt. Passt auf die kleinen und großen Philips Avent Natural Flaschen

Die Idee funktioniert, leider ist einer von vier undicht.

I bought these based on GRol&'s 14 May 2020 review stating they are compatible with Spectra bottles. However, I was misled. The instructions specifically state that they are NOT COMPATIBLE WITH SPECTRA BOTTLES. They indeed DO NOT and WILL LEAK milk all over the place.
