With 5 kids, we have tried LOTS of sippy cups over the years, some cheaper, some more expensive. I had never seen this sippy cup before, and I bought one originally in an emergency sippy cup situation. It ended up being my favorite sippy cup and I've bought several more since. Easy to clean, easy to close, easy to drink from and no leaks! And the price is great! The other day I couldn't track down one of the baby's milk cups and when it was found behind a night table 4 days later, I did not feel guilty tossing the whole thing in the trash.
