Negative Positive
Title: Comfortable... for the first week or two.
Review: I have been pumping almost exclusively since my baby was 2 months old (for the past 2.5 months). I am now on my third set of these shields. I have never put them in boiling water, the microwave, or the dishwasher - just regular hand washing. But they only last me about two weeks before they completely deform. The rubber stretches and leaves big stretched out bubbles which no longer adhere to my skin. The deforming has caused me significant nipple irritation. I also noticed that these used to be made of a thicker plastic before. My first set is much less flimsy than the other two sets I bought.
Is the review positive or negative?
