Considering the price, I think the voltrx protein shaker is quite good.
I hope they have metal mixed balls instead of clumpy plastic balls.
I used the metal stirring ball from the old electric shaker bottle.
Unless you use a voltrx protein shaker, there are too many compartments at the bottom.
Make sure the lid is completely closed.
Durability has yet to be determined. I don’t put the shaker in the dishwasher anymore. This is how the tip eventually breaks.
These bottles are so well done, I can put what I want into the protein bottle. But the ratio is wrong. There is not enough space in the powder container or liquid container. Before it can work perfectly, they need to make it bigger. I need more protein than this protein, so the protein I use usually requires more than 20 ounces of liquid. So, if your needs are different from mine, this bottle will suit you very well.
