I bought one with my Blue. I think it does the job well but I need to shorten the tube between the bulb and the bottle, a bit too long for me. I know it has probably saved me wasting the Floyd by dumping it in my hand and using too much.
I also bought one (smaller of course) for my Alt Innsbruck, which I was wasting by pouring.
I have trouble with using too much Alt Innsbruck when I pour on my hands. Where did you get a small atomizer for the Alt Innsbruck bottle?
I tried decanting a small amount Floid blue into a small plastic spray bottle. It seemed to work but it just took to much time decanting so I just splash on with my hands.
I never bought one, I like to splash it directly on one hand, rub both hands together and then apply to face with a light circular motion.
