This bottle is included with the WMF smoothie blender and it has given me so much that I immediately bought later me two more bottles. It is convenient because it is small enough to be deposited in the refrigerator and large enough to accommodate 2-3 servings Smoothies (approx 600ml). Thanks to the large opening they can also be easily cleaned, almost always enough a simple rinsing with hot water. In addition, it is made of BPA-free plastic, it should make sure all water bottles. There are certainly cheaper bottles, but this I can absolutely recommend!
