Not all anti-perspirant/deodorants work too well with me, but I love this one.  I purchased it in "Icy Burst" and it claims to provide 48-hour protection.  I think it definitely lives up to this promise (though I have not worn it without showering in a 48 hour period but... it seems to prevent me from getting sweaty or smelly in a normal day where I would usually feel a little gross by the end).  I will only be purchasing this deodorant from now on.
