I have used the protein shaker electric for at least 6 months, and the quality has not deteriorated at all. My electric shaker has only a few scratches because it was dropped during work and exercise, which only proves the durability of this thing. There is a small gap in the bottle mouth. I think you would call it a cage. Even that thing is very strong. Materials and manufacturing are important. The only problem I noticed is that the electric shaker is in the groove, the bottle head is screwed into the bottle body, and there is an O-ring to prevent leakage. This seal is particularly difficult to clean, leading to the growth of mold and bacteria, which is an obvious problem. I have tried using sponges, multi-tap nozzles, and dishwasher cleaning, but the effect is not good. Right now, I just use soap before some questions are prompted to reach the inside. If you use more than water, clean the electric shaker after each use. There is also a metal ball stirrer, which is provided with the electric shaker. It can help shake any sediment left on the bottom of the electric shaker. It is especially easy to clean because you can smooth it and scrub it with a sponge.
I have some protein powder. It’s so thin that it can’t be mixed with a spoon. It floats on the liquid. When I add bananas or frozen fruits, I use my Vita protein shaker bottle, but sometimes I just want to mix powder and milk. So I want to try Brandt. I suspect it’s because I mentioned it just now, but I can’t tell you how happy I am. After the milkshake was finished, the powder was completely mixed together without any signs of lumps; it was just a smooth, creamy drink. This is a good thing.
These 20 ounces are enough for me, but may be a bit small for some people. When you open the electric bottle shaker box, its size may surprise you.
