I bought a router from a company that had never made a router before.... Netduma R1 turned out to be one of my best purchases I had ever made back when I got it. As for the DEHP, there are fragrances that use this chemical too so I'm not really worried about the risk. The warning would just be legal matter, just like making an OS backwards compatible.
I am not intending to ever purchase the Razer router but you cannot deny that competition from a major electronics manufacturer like Razer is something Netduma and Netgear would ignore.
