Kenko 58 mm Circular Polarizer Polarizing Filter (CPL)

Hi,

I purchased this filter for my Nikkor 55-300 VR but the performance is some what not satisfactory. The ring is gettting faded and white surface behind the black coating is clearly visible. I never thought, i will get some thing like this from Flipkart. I am not blaming Flipkart, infactt there service asusual excellent on time delivery and good packging. But the product is not up to the mark. Hoya is any time better. Please do not go for this product.

Brought it ,may be 6 months ago.
Its good in bright day light . its really nice to see your photos saturated with not extra effort

but it gives different shades of colors (saturation) when you rotate it. (some time this helps as well)
M not sure whether it is the property of the glass or bad glass by manufacturing itself?
