I didn't test the 48hr feature. Sorry.
However, I'm going to assume most of you shower daily and over 24hrs, it was great. Kind of silky texture (I guess due to its special sensitive nature), inoffensive smell, generally pretty good and I'd definitely buy it as an alternative to my regular one.
Not a bad product. No itching that I sometimes get with other deodorants. Not terribly effective with eliminating underarm odour when very hot.
