Unfortunately, I was not paying attention and ordered this product. Delivery time was 4 weeks, there are free invitation included a 2 hour wait on main customs office. After a short tour together with the customs, I can only refuse to accept. A very cheap copy of the product offered in Germany, of course, without any marks. To use the risk this lamp was too big for me and by the way banned in Germany (the insurance coverage expires when using unverified products). All in all a new experience ..... read exactly where the product comes from
