Baby Product Alert: Thermos Straw Sippy

In the hunt for a non-plastic straw sippy water bottle for DS, I came across Thermos' range for children. They have sippy cups for infants, non-leak straw sippies for toddlers and even straw water bottles for older children.

See them all here: http://www.thermos.com/

I have always wondered what the differences were between the Foogo (range for toddlers, includes non-leak straw sippies) and the Funtainers (range for older children, includes non-leak straw water bottles, similar to the Foogo range). Well, here's a review if anyone's interested:

Klean Kanteen (high quality stainless steel bottles from the US) also has a sippy cup. Edited: Just wanted to make a correction - the Klean Kanteen sippies are also non-leak. They use the Avent sippy sprout.
