Query: Just as GOOD as Tupperware

All three of my kids love these cups (1yr, 4yr & 5yrs)they use these cups at home, in the car, at soccer. You name it you can bring these cups. Not only are these cheaper than the tupperware tumblers but they are easier for little hands to grasp. An A+++ in my book.
