This is not Mon Guerlain, this is a generic fruity floral. If you like Kenzo World and other pear compote scents, buy it. If you like lavender, patchouli and Guerlain vanilla, avoid. The top notes do sparkle beautifully like a sparkling wine though, but it's the only part of it that I enjoyed.
Disclaimer: I find most pear scents unexplainably difficult, cloyingly sweet and unbearable. Other people say it's the least sweet and freshest of Mon Guerlains, I can see where they're coming from, but my pear hating nose disagrees.
