The shipping of this product was very quick, arriving just a few days after I ordered them. These filters work very well, and I love having the wide range of levels to choose from. The only complaint that I have is that there are no markings on the lens to show where the polarizing effect is the strongest, and you can’t turn or adjust the polarizer when it is on the drone, making it somewhat difficult to get the best out of this feature. But once I find that sweet spot, the images look spectacular! I would recommend these to anyone looking to buy ND filters for there DJI Mavic Pro!
