Z1 just sales a product, they didn't steal anyone's idea, they are just a distributor and some of the items they sale are stolen ideas. At least they actually send you what you order and don't scam you by sending a knockoff part like another vendor has in the past (shall remain nameless). I have ordered a lot of products from them with only one mishap, which they more than made up for their mistake.
Kyle at IPP is great too. SpecialtyZ speaks for themselves, they don't have as many products, but they are very innovative and great to deal with.
