I bought this for my husband to use at work so that he won’t steal my things again. I have used it for more than two years, no problem. I think some people may put the lid on too tightly, which is why some people will crack. I like to shake the ball. It mixes everything together. Even if I use it every day, my original is still very strong and looks new, and I wash it in the dishwasher most of the time. highly recommended.
Voltrx blender bottles, mix the peanut butter into your protein and shake it, it is a very thick throat. But the extra protein is a good thing, isn’t it? It’s really perfect, and it has a handle. Just press the lid firmly, so that it can be fixed in place with a snap.
