Consumer Critique: Evenflo Toddler Cups

I recently had a chance to check out some Evenflo Toddler Cups: the Triple-Flo Tumbler and the Convenience Cup. The triple-flo is easy to adjust flow rate for younger toddlers who are getting used to cups. The valve is easy to take out for quick thorough cleaning. The convenience cup is a simple cup that helps protect from spills with kids who still need a little extra help with proper use. They're lightweight and inexpensive, so if they need to be thrown away it's not a huge budget issue; however, they're washable and recyclable as well! They'll be easy to find anywhere that baby products are sold.
