Definitely have a play around with various amounts of water, hand shaking vs blended, ice no ice, mixing in some milk etc. as above it's nothing like protein shakes and I'm perfectly happy with water + ice + blender, started off with oat or almond milk but it's a bit too thick for me.
Also got to try the madras today (sample pack) and it's a winner for me, lovely taste and much more filling than huel on it's own. I had two scoops around 5pm and I've only just started to feel hungry now (9pm). Texture is a little weird but i can get used to it, I'll probably add a bit more water next time so it's more like a dhal, avoid if you don't like spice as it's actually got some decent kick. I'll replace my lunch with it for a couple weeks and if I still like it I'll probably switch to it for the colder months.
