I am answering your question about spraying on the wrist or chest. I always spray on the chest - right in the middle of my chest and on the base of my neck. I find this gives the best reaction with my skin and body heat. I find that a spray on the wrist disappears more quickly. Colognes have different strength and projection, so you will need to figure out 1, 2 3 or more sprays required to get the result that's just right for you.
