Great Product Even With Slight Vignetting
I took this out for a little testing. I was able to get some good 60 second exposures on a bright sunny day. The sun was around 2p and no clouds in the sky.

On a couple of the photos at the river there is a showing of some slight vignetting in the upper left corner. It is easy to crop out, but it is there nonetheless. It should be noted that the vignette occurred at 24mm and I did have a CPL filter covering the ND1000.

There "may" be some color casting as well. It could have been the angle of my scene, however, and the CPL might have interfered. I won't knock it for color cast.

The magnetic design makes this so easy to use. When stacking, it can take some extra care to remove some of the filters without removing all of them.

Overall, I'm happy with these filters. I searched way too long among what is available at this time, and ended up with these. I'm glad I made the choice.
