My DD got it for Christmas and It has been awesome! Within two minutes of giving it to her, she was able to figure out how to use it. She chugged a good six ounces of water in just a few seconds it seemed like.
I am loving it, too. She is able to be so independent with it. I just give it to her while she is in her high chair or walker or whatever and she can drink herself thanks to the handles and the fact she doesn't needs to tilt it.....so thanks to Hellobee for the great gear rec!
Just had to sing its praises.
