As someone who is a high advocate of originality... how many different ways can you really describe the flex rod? Their entire e-mail was not copied word for word, only a single line was.
Honestly, it is obvious that Emisil looked long and hard at what RM was doing right, and produced their own version of it. If you have a problem with it, don't buy from Emisil; and never buy a phone or other technology, etc again because all companies are doing this --Taking from someone else and building upon it. It's something you have to deal with as an engineer of product. Expect it.
Emisil's products look very different from RM, they are not duplicates. At this point, idgaf how this product is being made, just as long as something is being made that meets our needs.. i'm not waiting over 6 months for a prosthetic to get delivered to me and i'm not going to spend $600 on something I don't really like.
RM has all of my respect. But if Emisil is able to produce something that fits my needs better than RM does, I am going to purchase from Emisil.
