Perfect for hobbyist use
I didn't want to spend a lot of money on the filter, now that I have a taste of my SLR camera and this one seemed good price and of course I think I got it right When I know anything else, I'm sure I want to try other guys, but for starters, this one is good for me. Comes with its hard plastic case for storage and fits perfectly into my lens. Happy with the purchase and the photos you take. I've put a few in so you can appreciate what it looks like with and without it.

Improvised my own!
Perfect fit for my Xiaomi 12s Ultra. I attached the magnetic mount to a generic case so that the glue won't damage the phone. Now I can take better daytime photos with my CPL filter.

Use as directed but no complaints
Quality build and with magnets, both of which I look forward to. Using the 82mm Polarizer on my Sony A7 with the 24-70mm 2.8 GM

The sample picture on the left is with the polarizer on the lens but turned "off" with rotation and the picture on the right is with it turned "on" with rotation. It has a smooth and snug feel but one that requires a little finesse. There is a sense of a secure magnet hold when putting on and taking off the filter. I only put it on for immediate use. The adapter ring however stays on which makes the original lens cap less secure but you can always switch to the magnetic one, your choice.

For me, I like it and would recommend it for landscapes.

Replaced a Kase filter
I lost a Kase magnetic cpl filter from my set and tried this as a hopeful replacement. It works great with the Kase magnetic mounts and step up rings. The quality is great and it was cheaper.

It's good but consider there is no glass filter in the magnetic field
I liked the quality of the glass and the ease to remove the filter. I erroneously thought the magnetic ring was going to have a clear glass on it and the filter would sit on top of it.
There is another package (which I found later) that does contain it but this doesn't. But hey! It does what it says on the tin. I misread and I just want that other people pay more attention than me

Easy of use
The magnetic fasteners are strong and efficient. Things attach easily, but are also easy to remove. Once you work with the gels they are easily attached and removed.

Does what it says on the tin
I bought this filter for the Sony lens. The filter delivers what it promises and for this good price. I can't find any defects, be it blurring or a black “X”. Clear recommendation.

Amazing CPL and superb magnetic system
At the first time I was afraid the quality of this filter but after some shots I'm sure that they are for professional use and the magnetic cover save me a lot of time to cover my lenses. I recommend this brand at 200%!
