Here is a piece of very honest bill: the body is black anodized aluminum, the rear mount (box side) is cut in the mass and well machined (probably CN). Said front frame has a metal insert comprising chrome slight internal burrs but without incidence (?); the assembly is carried out without sticking on both sides but above the target set has a radial play almost 1mm, without consequences. Disadvantage: -1) Is machined within very finely, so that the surface is almost brilliant; a stroke of good flat black paint should fix this problem. -2) The rear frame having no electrical contact, there is the case that may not be "in agreement" and refuse to run unless it is provided in the menu, so check before. ................ not like me
