PolarPro

Absolutely outstanding quality

Great filter but could do with a knob to make it easier to turn on those cold days or hot sweaty days IMHO, especially the 49mm which is quite small for my big fingers

Super interaction with staff that helped me get what I needed and I got it way faster than I initially thought I was supposed to get everything. Helix MagLock for the win!

I never opened the box. I returned it immediately. The drone that I bought it for was defective and I had to send it back. I'm buying a different model and will get filters for it soon.

Great and responsive service!
