This is a really great product. We a different volour for each member of our family and they are all used daily. They hold up very well. The one area that is most likely to be damaged is the straw. I take everything apart every evening, give them a hand wash and allow to dry. That said, one lid has been lost and one straw as keen cracked. As each bottle comes with three different lids, we have easily resolved the issues, but would really like to be able to buy replacement parts, particularly straws.
