Im am currently awaiting my first cup in the mail. One of the reasons I decided to make the switch was the idea that the cup was good for up to 10 years! I still find this hard to believe, and have heard that some companies suggest replacing them more frequently. My thought was that if they are all made out of medical grade silicone, shouldn't they last the same amount of time? Maybe companies suggest more frequent replacement to make more money.
Anywho, I was wondering if anyone had used a cup that long (or longer even), and how it has held up to long term ware. Im hoping mine can last up to 10 years (or until i have a baby, im 19 now so its possible that that might happen in the next decade).
So, how old is yours?
