I have exercised with this electric shaker bottle product for many years. The first bottle was lost (the typical black cap is transparent) and I bought a new one right away. I am very happy that I got this color because it is unique. I insist on the durability of blender bottle electric because my first one has been used by me for many years. If I don’t lose it, I will last longer. If I need another bottle, I will buy another bottle electric.
I have tried many blender bottle electrics, the best is the easiest to clean (easier than plastic grate). Please note that it takes a little force to completely close the lid-it closes in a 1/2 way, and it looks like it is closed, but if it is shaken in this state, it will cause bad luck. It will make a loud “pop” when it is completely closed, which is safe, but I still recommend holding it when it is actually shaking.
These shaker bottle electrics are really top quality. We bought two shaker electrics and replaced two old ones. The quality is obvious. It is worth a few dollars. We will buy these again.
