Curious if anyone has used or made their own version of the Blue arm.

I’m wondering what people’s experiences have been like using the Berkely Blue Arm. I think it came out sometime last year, but I’m curious if anyone has gone out of their way to build one or have purchased one. If you have used one, has it been easy? accurate? reliable?
