I purchased tommee tippee bottels and dummys for my son. I have barely used it and the writing is already off. I can measure the water anymore when I am making a bottel. Now I bought bottels for the 3rd time in six months and all of a sudden the bottels is blocked. My baby can't drink the milk through then. Nothing is stuck in the sucking section and not even water is coming through the tietie. Ive used tommee tippee with all three my children and its the first time I'm having all these problems. Not happy at all really. Now I need to go buy new bottels again don't think I will buy tommee tippee again
