I bought this shaker bottle just for the bulletproof coffee. I have been using this protein shaker bottle for two weeks now and the battery has 50% left. I highly recommend this ice shaker bottle and have no problem mixing ingredients. Ghee, peanut butter, mct oil, then hot coffee, I put the protein powder in and stirred for a while.
Press once to mix for 30 seconds, press twice to mix for 3 minutes, hold for 2 seconds to show battery level, press once to stop mixing. It doesn’t get any better than this. This is the official best shaker bottle Or is it?
