Company stands behind their products.
I had an issue with condensation getting between the lens when I was doing some night photography on Mt. Rainier...know what "dew point" refers to. The filter was way out of warranty but they asked me to ship it to thenm and they returned it with cleaned. It probably helps not to be demanding of much but they really went out of their way.

Non-planar distortions
The filter is variable all right. When I look through it and move it there are distortions noticeable in anything with a lined pattern. Apparently not very planar. I'll be returning it.

Not working well
It's sharp enough, it feels sturdy and well built, however I get a brown streak across the center of the image with this filter. I suppose it's a manufacturing defect or perhaps just bad glass? Anyways I recommend a better quality ND filter...

Great Value, works well.
I have found the Pro Optic 72mm Variable HD ND Filter, ND2 to ND400 to be a very good investment that has added to my ability to get those really good landscape and nature shots. The price was certainly right and the Pro Optic meets all my cuurent needs and expectations. The only negative comment is that upon receipt the besel ring and thus the outer lens were very loose. I tightened it but was somewhat disappointed at the lack of QA on the item.
