We bought this for the eldest son, he likes to drink a little protein shake every day to adapt to his activity level. This blender bottles are great. This is a screw cap that children can easily open and close. The grip of this sport is also very good, so it won’t slip. I have started to wash my hands, my other plastic utensils BC, and I have seen some seals damaged by the dishwasher. This blender bottles can only be washed by hand. The effect is very good! We have given up several times!
We use electrolyte drinks to mix, usually using the classic protein shaker bottle. We bought these for this design. Compared to the flap design, our 2-year-old child is more difficult to open. They look great and easy to clean. It’s like a rubber drop design. They will not leak, but if they do it the wrong way, there will be a few drops when they fly out and shake.
