Ordered simultaneously this filter and a normal density filter of Cokin. The filters provide individually on their own given the price good results, more than one filter at the same time the holder, however, makes for a very unpleasant magenta cast in the area of the graduated filter. Can be corrected only with difficulty in the post. However, the filters did not have the disadvantage that they seem to consist of butter at 50%. On my last trip I had the filter often change within a short time, and since I was not willing to pack every time into the protective sheath, they migrated often summarily only in your pocket - sweatpants, one filter per bag, no other objects, only in the state and while walking they landed back in the filter holder. Well, at some point I realized that the filter had a ton of mini scratch, despite very clean bags. In the course price no glass is to be expected, but as a soft material ... unexpected. If you treat them with great care and always well kept and used individually, they provide useful results. I have some really great photos shot with these filters, but who operates properly active landscape photography and know how fast one must be part of it will be understood that in the golden hour happy times do not have time to handle these things with kid gloves.
