This bottle is just great. We have been through a lot of bottles and we and the kids are united, these bottles are a hit. They are easy to clean because the shutter lets super disassemble. The wide bottle opening is great because you get no trouble with a brush or towel inside. It is dense and especially you can also fill in carbonated beverages.
To the these bottles also look great, our little girl loves this bottle and we will definitely get even what USN. Thumbs up... :-)
