I have been living off soylent/Queal/Huel since Feb 2015 and Huel is by far the better option. Just one tip for the shaker: http://tinyurl.com/jc8aflx.
The blending ball in the link above allows for smoother shakes without the need to use the blender! - even less washing up!
Hopefully it can be integrated to the existing shaker which, in my experience, is fantastic, no leakages and very decent quality.
Cheers
