I have their PSMM and its one of the best mounts on my car. Craftsmanship, quality of materials, and customer service is top notch. I cant speak for the RMM, but if its as good as their other mounts you cant go wrong.Thinking of getting a Damond RMM from them but don't know anything about them. Was referred by a friends friend that owns a MS3 about them. Anyone have one or know anything about them?
