If for your nutrition shakes are important then this is a really good machine for on investment. I have to say did protein shakes need to be shaked before with on hand shaker 30 seconds and Then They Can Be worked with Bartscher for about 2 minutes, this is the way to avoid any lump and have always a perfect shake. You can not obtain the same result with only the hand shaker and viceversa. It is easy to wash, you have to fill the cup with some hot water and then switch on the device for 30 seconds: simply and effective. have fun!
