2017 Model The Plant-Based Milk Maker

Is it possible with this machine to produce any milk of those : oat, rice, soy?

does anyone know how this compares to the Soyabella, which is cheaper?

What's the minimum and maximum amounts of water you can use with one cup of almonds?

I find it very hard to use 2cups of almonds, the blade cannot go inside the cup easily because its filled with almond, what am i doing wrong?
