I recently got the starter box (I love the vitaminbars!) and started with the banana flavour. I mixed it with 400ml water and I felt like it didn't feel smooth to drink. The consistency was so bad it made me feel like I was going to gag, not a good start! I tried mixing in some unhealthy sugary chocolate powder to make it more palatable (it barely made it better) and eventually finished it. There weren't really big chunks but it didn't feel smooth - felt like small particles in it. So it didn't feel smooth but it still felt too water-y. I don't know how to describe it 
Then I tried mixing the oaty vanilla flavour with 100ml oatdrink (oatly) and 250ml water. That was a bit better I guess but the consistency still felt about the same. I didn't even end up finishing it. Felt like small particles but yet too watery and too yet too gooey at the same time, I don't even know...
Now however, I tried the forest fruit flavour with 350ml water and I shuck it rigorously for 60 seconds and it's delicious! Previously I felt the others were too watery, but this is even more liquidy but feels so smooth to drink. Feels great! Only downside is that after having each sip there feels like there's dust in my mouth, but it's not too bad. Feels like small particles that don't dissolve/mix properly but not sure how to get rid of that.
So I'm not sure why my experience ended up being so different between the different flavors. The oat one is understandable because I mixed with oatly. I'm going to consider buying one of each and mix with 350ml water and hope the consistency is the same as this forest fruit one because this one turned out nice. Is the consistency supposed to be the same/similar between each flavor?
That's my first experience with Jake! The vitaminbars were delicious (more flavours please!)
