To be honest I wonder how carefully they where checking the teat cause I have used happy baby dummies at work and at home for years and the first signs of wear on the teat out they go. I find the teat almost impossible to rip off if they are intact but with a hole in them it is much easier. I think the only other cherry ones I have seen are the tommee tippee ones but I don't think the actual teat part is as big.
