On my two bottles anyway, it's not a seal, just a cellophane strip around the cap with yet more programming on it....I thought it smelled great when I first tried it, more soft and powdery than refreshing and pungent...what I have noticed is that it really does linger on the clothes after they are dried, more so than other liquids with built-in softeners. I like it, but am not confident that it has a lot of stain-removing power, which is probably inherent in these combination products (my much-lamented Solo liquid was the same way).
I'd say that it's not "Cool Water", "Eternity For Men", or even Jean-Paul Gaultier, but if you are repelled by "Tide with Downy"'s or "Gain With A Touch Of Softness"'s flowery fragrances, there's a shot this might be a little more pleasing.
For what it's worth, I think of this as my new "Woolite" (always hated that stuff!)
