The Xintd X3 has some issues with its anodization I discovered. It looks great, but it gets damaged pretty easily. I put mine in a bag with 2 other lights (no protection) and after taking them out of the bag, the xintd got some clear blemishes on different parts of the light...
So if someone is thinking about buying the Xintd X3, just keep in mind that it's anodization isn't really strong!!!!!
