Very cool design and 2/3 the price of their competitor. I rarely shoot in situations where a CPL is needed but am occasionally challenged by conditions where a CPL comes in handy (event photography) - this then becomes a very attractive option versus trying to quickly screw and CPL on and off while "running and gunning".

High Quality and magnetic attachment is strong. No worry about it falling off. The problem is the CPL is very hard to rotate. With a lens hood on even more so and on my 100-400 with the small opening in the hood, next to impossible. This system with filters that you don?t have to rotate is excellent.

Technically, the filter works just fine, however, neither the lens cap nor the filter will stay on after the slightest bump. On a tripod all works well, but during a walkaround my filter/lens cap fell off frequently. Good idea, great filter, but just not quite ready for prime time.

I use this thing all the time, no complaints
A very high quality magnetic mount polarizer with a magnetic lens cap. A great setup that I am now preferring over using the Sony clip on lens cap. This polarizer only removes unwanted glare and doesn't add any other unwanted image changes. Best used outdoors on sunny or partly cloudy days to remove glare and also add definition to clouds and also slightly darken the sky to add a bit more color and richness to blue skies. Highly recommend.
The filter works very well and due to the magnetic ring can be installed very easily. The ring even has a thread so you can use existing screw-on filter without having to remove the magnetic ring. I particularly like the magnetic lens cap. The magnets so far have been strong enough to hold everything in place.
