After using the medela symphony for 5 months we finally had to give it back & buy one. I chose the ameda purely yours & although I've only used it for 3 days I have to say I'm not a fan. 1) way louder & stupid beeping is annoying enough to prevent letdown 2)letdown can be a craps shoot it seems. I use it approx 5x/day when @ work & almost half of those times it took almost 20 min to get an initial letdown & then takes another 20_30 min to drain the milk. Once it gets going, though, I get more letdowns in a shorter amount of time than the medela. 3)the 'horns' aren't like the medela at all & because of that all the bras I retrofitted to be handsfree are useless. I am able to use a nursing bra to hold on bottom & top of shields but is precarious & if I massage while pumping this doesn't work. Anyone else using the ameda purely yours have any tips?
