Bests & Worsts Reviews from Amazon

I ordered this perfume in September of 2013 and have used as my daily fragrance consistently since that time. I had noticed a handful of reviews with thoughts that this product may be fake. I chose to ignore these since initially the quality seemed to be authentic, and I routinely received compliments on how lovely it smells. Over the last couple months of, I noticed the general strength of the scent was declining, however it still maintained the same fragrance. Today, I spritzed on my usual two sprays and it was like I had doused myself in rubbing alcohol. Overnight, the scent seems to have completely deteriorated. It has been about an hour now and the rubbing alcohol smell has dissipated, but the scent of the perfume is incredibly weak. I am so disappointed seeing as I have not even owned this bottle for a year and it is only about a third of the way gone. I've worn perfume and sprays for years and have never had one go rancid this quickly. Will not be reordering and I am extremely disappointed in the quality, especially considering it was sold by Amazon.com.
