I agree with Mike's review dated 5/28/2019 - something is different. Like Mike, we've been using this fragrance for years and always loved the outcome. We purchase the same fragrance from several sources, but always liked the Candle Science formula. The fragrance today seems to be a bit weaker in the bottle than in the past. But once in the candle the scent is very weak; and when you burn it there's almost nothing.
I have candles made from this FO that are several years old, and they still smell amazing today. But no longer. Something is different. It's not bad, just not as strong as before.
