Too bad it doesn't work for you; for me, it's just the right dose of the original M7. Opium d'Orient, last years version of that was nice, yet very short lived. The one this year was just - hm. Too close to the original. I own the regular Opium EdT and it's reserved for sub-zero-celsius days.
I guess I agree there's no real merit in M7 Fresh if you already like and wear M7. But for those that find M7 too evil, like I do, it's a nice version.
