I was really weary about buying a spray on deodorant! I usually use a clinical strength deodorant because normal deodorant don't work for me! But I thought I'd give this a try!! I'm so glad I did!! This deodorant last me TWO DAYS!! I can't believe how well it works! I spray two sprays under my arms rub my armpit against my arm and it takes about two minutes to dry!! But it works!! I definitely will purchase again!! Just wish it was a bigger bottle!
