Arrived Quickly Build quality excellent. One of the best filters available no doubt.Very color neutral.Compare to anyone!

Works great. Haven't used all of the filters yet but they are decent quality. Id buy again.

Amazing. Amazing quality sound, crisp, loud, and having pop filters and extra makes it even better.

Kai Pei created this lens and takes such great pride in his creation he includes video instructions in the impressively packed package. The lenses themselves are made of quality material, not plastic. They are extremely well made with a heavy, sturdy feel and big enough you can easily handle them. Can you tell I'm impressed? Completely impressed as this is my second wide angle lens to order in 2 weeks and the first one doesn't even compare in the least to the quality of the xenvo. It fits perfectly on my iphone Xr with my case on! I will be taking a trip to Maui in a week and bought the wide angle lens to use for landscape photos n such. Will update this review with pics once I get back. I didn't really care about the macro lens, but after watching the tutorial video I can see how it will come in very handy for flowers and rocks/sea shells while I'm there. Can't wait to put these lenses to the test. And bonus, you get a very well made led light that has 3 settings to clip on your phone that can help enhance your macro photos.Updating review with pictures from my trip. Loved having this lens with me for all the landscape photos I took.

Been a sucker for this brand for ages now and finally got these to go along with the Grads filters. Great quality and build with very little colour cast.

Quality product and speedy delivery. I've put these filters in my cars for years. Great investment!

Great - can't believe how much I used to pay for poor quality filters!

I purchased numerous filters from K/N & the Quality is really there, Hex nut is a sure plus for installing & removal.
