Q: I've had this product for two years. The first one was used by my children as their own personal water bottles with no problems. They are pretty hard to get clean and I couldn't see how the lids could be better so that's something that would keep me from buying another set of these. However, they started showing signs of rust after only 2 years use, so I bought a new set. My boys really don't drink much water, but it wasn't anything like the time we had them.
A:
Good Review
