I bought this smashbox photo finish primer dupe off of ebay after reading about it in a magazine. The product is indeed very similar in appearance to the smashbox primer and the consistency is also similar, but this is where the similarity ends. This product did not work nearly as well as smashbox either in terms of facilitating foundation/MU application or in preserving mu. Everything was gone, gone, gone a very few hours after application. This was cheap on ebay but I can't say how much it costs retail. Still, even cheap is not a good deal when it does not work. It also has a slightly unpleasant odor. I don't recommend this to anyone I'm afraid.
