Mixes very well. The As Seen on TV had one of these type mixers years ago; but not as good as the Quality of this one.
I drink a green drink each day and I used to use a stainless steel straw and a big stainless steel cup. But no matter how I mixed it up, it always sloshed all over and inevitably I have to mix it up over and over again as it settles and that’s no good. I was worried this Vortex mixer on the go mug would not have enough power but it is perfect. Now I’m thinking of all of the other uses for it like pancake batter. Uses two batteries in the bottom and I can easily take it on the go. I also shook it by hand and turned it upside down to make sure it would not spill and it was secure. Love this! Thank you. I hope you keep this in stock.
