I still am optimistic about the idea and principles behind Soylent, but I got to say, I was not impressed with their initial product (v 1.0 and 1.1).
It gives users horrific smelling gas, and honestly, I generally felt worse on Soylent than after any other type of food I have ever eaten, including junk food. (I didn't mind the taste though.)
They are already at v 1.3 though. Here's hoping that this capital influx allows them to rapidly improve the recipe.
