Today received my diffusers from Stephen in Germany. They look very good and fit well. They are black with a crinkle finish, so if you would like to paint them they should take a coating well following recommended fiberglass procedures.
They came to me in good condition, but the box was beat, torn and resealed by the USPS. Stephen gives you the option to insure the shipment and I would recommend paying the additional charge for the insurance. 18 days shipping time.
