We all have our opinion. I read a list on filters that msinger put out. There is better filters then Polar Pro, but you pay the price. Hey, you get what you pay for. The one that was just below Polar Pro was way cheaper. Maybe msinger sill has that list?
Sorry about my old memory. I have Polar Pro. I also bought the one I think was below it and I see no difference. They fit perfectly and weight the same as the factory uv filter on my P4. I don't want to lead you wrong, so try to get msinger's list.
