They were great at first, but they are NOT bite proof. My son loved them, they are easy to use. If your kid has teeth, they are easily destroyed. I went through several of these before switching to the 360 cups. They are easily portable, and easy to clean.

We absolutely love these cups! They are very easy to wash, dishwasher safe and very easy to take apart for a deep wash. The leak proof technology is great, it has definitely stood the test of a toddler constantly throwing it across the room. Love these!

Excellent value for money for a really durable and leak proof bottle, great design as little hands can hold it easily and holds a decent amount of water in it. Easy to clean.
