Priced the product is out of competition. Quality and appearance make a good impression. Unfortunately, the clip despite fully tightened adjusting screw a little game on the lens. I have therefore that the rubber on the inside of the clamp somewhat strengthened. Now the clip is firmly and I am very happy with the product.
4 stars for the price / performance ratio.
Actually, I'm a friend of original parts and buy reluctant copies. But here, the pain threshold was exceeded. The original is "extremely naughty too expensive".
