Device is extremely well designed and documented. I originally thought it was too expensive given what it is, but this is not going to be a high-volume product and it took some decent effort on their part to lay it out so the price is more than justified in my opinion. Plus the support is there which is great. When you consider this more through the lens of a research product, and not a hobby product, this is actually pretty cheap. Very nice. Will probably buy more as needed.
