“The glass bottles are of good quality, but there are several flaws in the design:
1) The bottle lids (holding the teat) don't fasten properly. This resulted in it coming undone and my baby being covered in milk - very much not appreciated.
2) The "stylish" bottle markings are imprecise, which is not helpful if you're trying to measure out exact amounts.
3) The set only comes with slow-flow teats, annoying if you have an older child.
The teats (again borrowed from another brand) are good however, with the addition of a second anti-colic valve.”
