Hey Aravind, sorry your shaker doesn’t fit in your car cup holder. Unfortunately there are no universal car cup holder sizes so it would be difficult to find/make a shaker that both universally fitted every car in the world but also wasn’t so small that you couldn’t adequately blend Huel. We also wouldn’t want to encourage people to have their Huel whilst they are driving as it could be dangerous.
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.
