The only con is that the cup does not fit in her car seat cup holder. It's the only sippy cup my daughter will drink from. I want to order an extra set because my nieces and nephews liked them too.

The cap also has some crevasses that might be hard to get to. Stays mold free for a good while. And it's never spilled out everywhere.

The straw is nice and wide so it’s easy to use those small * brushes to thoroughly clean the inside of the straw. Since it has a built in tube, you got to have a special stick brush to clean.

My son likes to throw his sippy cups off his highchair. This cup lodged milk into the threads so that when i picked the cup up it dripped all over. Bottles are only okay for the hassle.
