From the first purchases I made, waiting for the birth of my little one. What I have to say in general is that we preferred Avent products and we were not disappointed. They are very high quality. In this case, it was worth every penny and more. BUT the only objection I have is that the silicone nipples from Avent are too hard for newborns. Our baby couldn't suck the milk as a newborn and we started using them I think from the third month onwards. Until then, we used another brand's rubber nipples, which were softer. However, 18 months after the birth of the child, I can say that we did not encounter any problems with this product. All Avent nipples and pacifiers did not have the slightest tear and are intact. The little one did not have any problems either. The bottles are very convenient, as well as the cleaning brush. I recommend it for new parents, the Avent brand is a guarantee of quality. I give it 4/5 stars only because the nipples are hard for newborns, as mentioned above.

UPDATE: Three years after the birth of my son, I can say that Avent bottles are among the best on the market. Not a single nipple broke (unlike nipples from another brand that melted/cut), the little one had no problems and even recently used them to drink milk. Truly durable, both for the nipples and the bottles, which despite falls and washing, did not suffer any damage (both the plastic and glass ones). The same of course applies to the pacifiers... they give you the impression that you can use them normally for the second child too!
