This filter is well made and features a metal ring that is easy to hold and rotate. At first glance it is not a slim or flat ring, being thicker than my other slim filters. The concern relates to possible vignetting when using a wide angle lens. The product description claimed that it can be up to 14mm wide without vignetting. While I don't have an extra-wide lens that wide, I tested it on a 12mm fourth-third lens, which is equivalent to a 24mm full-frame wide-angle lens, and I saw no signs of vignetting and the ring is lighter hold and rotate than some ultra-thin filters. Overall, this filter offers good value for money and is cost effective to protect your lens.

Like it. Low cost, giftable, neighbors want to borrow it already

As you can see from the picture, as the heigh can change, and the light direction can change, it is very useful when I need the light at different height and angle.

Compact, light, bright. Well structured and reliable

Low cost, well made tripod with a decent carry case too. No complaints
