The metal ring, which the zusammenfaltmechanik is made possible at a location open and there joined by a clamp, which fold up at my copy after the second broke (was bent by the forces) this meant that the metal ring durstieß the fabric of the reflector = total loss. The metal ring must be welded, as is the product after a few uses of useless junk.
Otherwise, the reflector is processed tadelos and high quality.
