Review: Happy with my purchase - I had been looking for inserts for my Elvie for quite some time. I didn’t want to spend a lot of money for them not to work. I’d seen people mention these inserts so thought I would give them a try and I’m glad I did. I had to cut them to fit the Elvie flange but it wasn’t hard and they have made pumping so much more comfortable. Great product. Thanks!
