I've been using this spray for a year or so now and I love it. It's a classic for good reason.
Easy to use, lasts for ages and gives you that classic fresh and clean smell while going about your day. Some deodorants don't last through the day and you find yourself getting a little smelly on a hot day - although you can still get that with this one on a really hot day, or after a hard workout, it definitely tames it down compared to other one's I've used.
Does not clash with perfumes or creams so you can still wear your favourite scents. No white marks on clothes either.
This aerosol can comes well presented. Using from the recommended distance (15-20 cm) directly onto skin can help avoid clumping of product which leaves white lumps on your skin. It smells great! Just like soap, so using directly after a shower is a bonus to help keep the freshness all day. I find it lasts for myself, a good 8 hours with regular activity. I'd say if you were to do exercise or something strenuous maybe use a roll on also.
