Does anyone use the munchkin mighty grip cups?

[BeccaB.]

I bought the munchkin Sippy cups about a month to 2 months ago and have already had the silicone spouts break on 3 of them. I wrote to the company about the problem and they said they sell replacement spouts. No info on how not to break them or even a sorry our product broke.

Now I have sippys that dont have tops. I cant decide if I should spend money to replace the tops or just cut my loses and ditch the cups. What would you do?

I got a couple of these about three weeks ago and so far have had no problems. Thanks for the warning though. I got the Munchkin Mighty Grip Flip Straw Cups at the same time and we alternate between them and the sippy. Since these have been DS's favorites out of everything that we've tried, I would probably buy the replacement spouts.
