Anyone tried a variable ND filter?

PGYTech has one. Better than a set?

I have a freewell variable nd filter and it works very well
At the higher stop levels there can be some vignetting on open sky areas

I have the Moment variable filter set. One is 2-5, the other is 6-9. I am very happy with them.
