Not sure about the rest of the material taught on the DVD - the clipshift itself is very similar to the "flexible shift" taught on "The Session" DVD... 2006, I think. If used as a utility control - can't speak for the colour change.
Queenie, given that you're a "pass - as - colour - change" person, it's probably right up your street

I for one won't be putting in the time required as I can think of a trillion* other sleights that are probably more worthy, but depending on your commitment to being a "card techie", go for it.
*mild exaggeration. Hey, it's Christmas eve/day, I deserve to be p*ssed.
