Very good quality. Have other brands and this seems to be very well built. Follow directions the first time you use it. Will make everything go together as it should. Optics seem to be very good.
My filters fit better now and even a welders glass fits fine!
My filters fit better now in this new housing design yup here 3 photo's I took with a weldersglass. the dark one even had the polarizer in the perfect housing
This product is the first of it's type I have tried it works as it should look solid no light leaks that I can detect. Color on the photos looks good. I am using Lutz filters with it. So far I am very satisfied.
