I like these portable mixers very much. I bought different colors and sizes. They can enter the dishwasher. I put them on top of the dishwasher over and over again without any problems. They never leak and are tough plastic. The color is very beautiful. The only problem I have with them is the portable protein mixer. If I drink cold drinks, they will condense on the outside. So I always put it on a coaster or folded paper towel. The quality of protein bottle electric is so good, it’s worth spending a little more money.
My wife used to go to work without breakfast. By lunch time, she was obviously hungry. It was not ideal for nutrition and health. She bought several such vortex portable mixers, and she did not drink protein shakes at work in the morning. She ate something for breakfast and did not starve to death during lunch. They can be cleaned in the dishwasher (only on the top shelf), and the stainless steel stirring balls can be placed in the silverware box. The shaker bottle is easy to clean and reuse. Winner!
