Excessive vignetting.
Is reasonably accurate as far as 10 stops is concerned. Only a slight difference in exposure between 30th and 30 seconds. Colour cast isn't too much of a problem, some trial and error will let you know how much to offset your wb for each light source. Biggest issue the excessive vignette this filter causes. I would not recommend this filter for that problem alone.
