Why the hostility? OP didn't claim they are an RPF1 replacement, or that people should be buying these instead of RPF1s, just that he liked that there is a similarly light, and better looking wheel.
On durability:
It's unlikely this wheel will be significantly weaker than RPF1's either, and it uses an I beam spoke design that has been proven in many other reputable wheels to trim weight.
You can typically assume similar strengths at similar weights given the same manufacturing process and reasonable wheel design.
