The Huel shaker is off the shelf and works excellently for mixability, not bespoke to us. Your method of mixing isn’t typical of what most customers want to do, shaking for 60 seconds would be extremely odd to put in the Let’s Get Started booklet. You may well get good results for smoothness from using warm water, but we don’t recommend using warm water, we recommend using ice cold water because we believe it tastes far better. We need the extra room to allow for space to shake thoroughly in a shorter time.
Having our own shaker would be amazing but see below message on this.
The shakers are in equal parts perfect and not ideal for different reasons. We would love to have our own shaker, we tried over a year ago to do this but many prototypes later we just simply didn’t have a solution that was better than our current shaker. Sorry about that. When we have more time, this will sure be a project we look into further.
