Don't buy the new Coppertone Continuous Spray, unless you realize that you must treat it like any other suntan lotion and rub it in, plus have help with your back. The spray feature does not make it special. In fact, it lulls you into thinking that spraying will be enough.
Here I am on Monday, with a burn on my back so severe that it still hurts from last Wednesday, and I know this product does not work the way it appears to, although I loved the theory of it. Don't trust that the luxury of being able to spray your back on your own will be enough.
Oh yeah, consider what happens when you spray suntan lotion in the wind. Lotta good it does.
However, I sprayed my back indoors, Miss Sun Phobic who preps ahead of time for the sun due to extreme sun sensitivity, and it still didn't work.
Save your money. I trashed it on the ship.
