Well since you brought up surefire in your original post I will go ahead and say it these aren't Surefires. That said I have owned multiple fenix lights and they are one of the better quality Chinese lights. Myself I prefer JetBeam for Chinese lights. They have always seemed more refined and a sturdier light to me. I agree 4sevens is top notch service. I have also used deal extreme and they are a good importer for Chinese stuff and knockoff lights also they have all types of Chinese junk for cheap.
