Disappointing Wait Times
The last two, maybe 3 products I've ordered from Polar Pro almost seem almost like Kickstarter programs since I send you money (unlike Kickstarter, there's no "Earlybird Discount") and then wait months to get the item. Meanwhile, every other filter company (like FreeWell, K&F, Tiffen, Newer, etc) have product ready to go on their websites and Amazon almost on the day the camera/ Drone is released. The worst problem I have now is the unnotified delays. . . as in the product I ordered was supposed to be shipped on one date when I ordered it but that day has come and gone. So I check on the website only to find that the ship date has changed. I contact Customer Support to be told, "Oh yea, there have been manufacturing delays, sorry". A notice would have been nice, just saying.
At one time, Polar Pro's premium quality made them worth the higher cost and potential wait but to be honest, I have a hard time these days differentiating them from products costing half as much, that arrive a couple days after you order them.
