As the full range: perfect!

I was surprised by the plastic (already having the same kit but glass).
Always so satisfied with the quality. I have a lot of product in this range, and all are good.
The brush, either like or not like it. It is not like conventional sprinklers, but allows easy cleaning and especially not splash when removed from the bottle.
Two small caveats: transparent teats does not make it easy to read the number when it is full of milk, and the tip of the cleaning brush seems unsuitable to me to clean the teat (I'm afraid of spoiling ).
Otherwise, perfect!
