Floris Shaving Oil

Has anyone here shaved with this No. 89 Shaving Oil, either by itself or along with another No. 89 product? It's pricey, but the instructions are to use just 2-3 drops. I'm curious about how a shave with it would compare to a shave with the soap or cream (other than removing the pleasure of using a brush).
