I really like it and wished it lasted longer

I never had Gucci Guilty Black so I can't critique its exactness to the original, but definitely has no staying power. Lasts maybe 1-2 hours. As for fragrance, I really like it and wished it lasted longer, maybe 5-7 hours- it's very pleasant. Here's to hoping they make a perfume version that lasts longer. Honestly, I'm not sure if I would recommend it or buy it again, though. I'll leave the risk taking to you.
