Review on Neutral Density Premium Gorilla Multi Pack by Shree Carmean

I love their quality. Much better than other ND filters I've bought for various iPhones over the years. I'm new to my Hero9 and figured I need ND filters for good results in the mountains on sunny days with no cloud cover. They arrived quickly in a nice mount and after a little practice (how to just open the door to change the battery or change memory cards) the filter works well and stays in place. It takes some practice to get them on and off comfortably, but the results of my shots are worth learning. I found that the presence of a silicone cover also guarantees protection of the filters. Some silicone cases come with a lens cap and I really appreciate that. Great quality and great price. They are highly recommended for your hero!
