I shoot photography semi professionally and needed a good CPL after watching YouTube reviews I popped on this for my canon t7 with EFS lenses it disappeared perfectly, stays on (sometimes to good can be a lil tough coming off), picture quality is great (I run manual always), hasn’t scratched or discolored yet it’s been like 2 years almost with near daily used mainly in the woods/nature, threads are okay that’s probably the only “2 complaints” if you’d call them such I have, first the lens cap (stock canon 58mm) do not hold onto the CPL so travel with caution and keep tabs on your lens cap or you’ll be buying more! And second it binds a little going on every now and then if they’d clean them up a shade and maybe get lens caps to hold tighter for travel this CPL would be and really is the best bang for the buck in my eyes! Yeah you can buy crazy expensive stuff but on a budget for non pro use definitely get you one! Once I finally do this one in I’ll be buying another. Oh and super important it comes in its own hard case for storage/travel with foam and it locks shut so it’s safe, I’ve had it in my camera bag and climber mountains and it’s stayed in the case no issues that’s definitely a plus i needed to mention.
