Since taking up running and a more active lifestyle, I've discovered I need a stronger deodorant - as keeping fit is sweaty business!! . I usually use Mitchum deodorant - roller, but decided to try clinical.
It's fantastic at controlling the sweat, and keeping odor at bay with my exercising, and it's also great during the day on the warmer days, keeping me dry and no odor! I put this on at night so it gets to work while I sleep and let it do its thing!
My only gripe (hence not 5 stars) is the winding mechanism is a little stiff at times. I just use one click per arm. It is a little pricier, and definitely doesn't last as long as a roller - but it is great at controlling sweating - especially for the really active sweaters :-)
Personally i find gel deodorants strange. Im not sure what it is i just do. This worked but wasn't my favourite.
