Short review: Basically identical to Kalan in the air. I prefer Innovator over Kalan as to me it smells better blended whilst projecting and lasting about the same amount of time. Long review: I tested the 13ml spray next to a decant of Kalan. Overall this is about 95% the same as Kalan. Like Kalan, I get 3 main notes - Blood orange, spices and woods (vetiver). Innovator has a slightly sweeter orange, less astringent spices and the woods aren’t as aggressive or soapy. Overall it comes across better blended and smoother. When sprayed the orange starts off subtle and not a big blast like Kalan but give it 20-30 minutes to settle and it becomes almost identical to Kalan as the orange really pops out. I had 2 friends try both and they also preferred Innovator. If you want to know what Kalan smells like then try this. It has also grown on me the more I wear it.
