Review on PROMiXX MiiXR+ PLUS Electric Protein Shaker Bottle - Device-Charging Vortex Mixer for Smooth Shakes & Supplements, Shake Bottle Blender, Mixer Cup, 20oz Tritan (Stealth Black) by Aaron Gonzalez

Promixx pleasantly surprised me. I take it to work every day with an afternoon snack to keep myself in check. I never liked shaking the protein powder to mix it, there were always some lumps. What I like about Promixx is that it keeps powder and water separate for storage. 2. It mixes powder with liquid completely. 3. easy to clean. What I don't like is that the spout lid closes more securely. This is an airtight fit that uses friction to hold the connector in place. The bottle can wobble in my day bag. I just don't like that Promixx isn't stored vertically. A clip on spout or threaded spout cap makes it the perfect solution. In a number of reviews it appears that this is a blender but it is not. It's simply a solution for mixing powdered drink with a liquid. But it's great!
