The bottom line on this, as I see it, is that either the Haimer is a patented product and they will pursue their legal rights or it’s not a patented product and it’s fair game.
I don’t think that someone would attempt this within the US knowing that they would be legally pursued. From China or another place overseas, sure, but here in the US you would have to know that eventually you will lose.
Could this just be a scam to raise funds and never deliver, perhaps. Hard to tell without greater research, and I for one am not willing to dig that deep. I suspect, based upon the BIO of the founder of the company doing this (DDR, Direct Drive Robotics), and this is assuming that the BIO is legit, that he is not going into this blindly.
I have supported a few kickstarter campaigns over the years to help out an upstart, and so far have always received what I paid for. But this time around I just can’t see how this would be of enough benefit in my usage to justify the cost. This is certainly a great time saving tool, but it doesn’t seem to do anything more than other tools that I already have can do.
