I love the avent bottles but we have broken them at least 4 times mainly from our son dropin them out the car our accidentally hiding it on the granite wile washing dishes.I was getting tired of dealing with a broken glass bottles so I decided to look around and came across Olababy and decided to purchase a bunch of the silicone Protectors and I am so glad I did these things are holding out well for us.
I bought these to fit my Avent glass bottles. They fit, but really are not snug once they are on. I don’t know what to do to make them fit more tightly! I followed the directions, but when they are on they are a little loose and the grip is not tight. They are almost a little more annoying to have on the bottle. I would rate them higher if I could figure out a way to make them fit tightly against the glass.
