Klean Kanteen Sippy Cups (12 oz)Product Rating: Product Review (submitted on August 22, 2012):
I bought this sippy spout kanteen for my 1 year old daughter 3 years ago. I am STILL using the same kanteen, only now with a sports cap. I bought one for my son who is now 2 as well. Aside from replacing the spout for the sippy cup a few times the cups are still holding up for Kindergarten. They dint a bit on the bottom when they are dropped on cement or other hard surfaces and are a bit scratched up but are still going strong!
I love the fact that they are easily washed and if they are forgotten about in a bag for a few days, they do not mold. A simply swish of vinegar cleans them up as good as new inside as well if they need to be thoroughly cleaned. Well worth the money, you'll pay 5x that amount over the course of a few years in cheap plastic ones.
