These inflations pull the milk away from the teats very quickly. I still personally prefer our basic inflation setup for its simplicity but was very happy with the performance of the TopFlow inflations when testing them. The green “cage” around the inflation allows for easy attachment to the teats. Sliding it up or down turns the vacuum on and off to the inflations. One other benefit is ease of removal from teats without pulling on the teats.
