ebow86, as has been said before by many, including myself, the defects you have mentioned is normal. It is not a defect per say but if you are unhappy then send it back. Mismatched ano is normal too. Unlike some other brands, SF anodize their parts individually (bezel, tube, & tail cap) to control the thickness of the anodizing and there is no way to ensure the ano color would come out consistent. If it does appear to match then you have strike the lottery. One reason why many manufacturer chose to use black for ano instead of leaving it natural is because it is easier to do black anodizing and maintain consistency in color from light to light. Chinese made lights seem perfectly matched in ano because they just dip everything into the tank. My experience with Chinese made lights shows that a lot of them either never give you real HA III but claimed they did, or they have such a thin layer it wears in a few weeks or couple months of usage. I have an SF M2 which has been with me way before I join CPF, and other than some dings from me dropping it, the anodizing is still perfect. Can't say that for my Chinese lights.
Give SF another chance to make it right. If by then you are not happy then ask for a refund. Honestly, we have not seen a single photo of your light and have no idea how bad the light may be based on your description alone.
