I've been using MUM for years now, and I find it the most reliable anti perspirant on the market. I use the Fresh Pink which is a lovely subtle fragrance. It's a roll on deodrant that does take a little while to dry and if you're wearing black be careful how you put your clothes on as it can leave white marksif it's not completely dry. To be honest though, I'm prepared to wait a little onger until it's dry and be confident I have a good product on that will keep me fresh all day than have one that claims it will dry instantly and not leave marks, as I've found these type of products can fall down on performance. The only thing I will say against MUM is that they used to use plastic bottles, and now use glass. I understand the glass is recyclabl,e but you cannot remove the plastic roll on part from the top ,so you have to throw the empty bottle in normal rubbish anyway. Also, it's makes it so much heavier and more dangerous to carry, as I often carry mine around in my swimming bag.
