Deodorant is pointless IMO. Your body doesn't stink, it's the perspiration and lack of personal hygiene that makes it stink. Shower in the morning everyday and use anti-perspirant. If you ever need to use deodorant, you need a shower.
Anti-Perspirant: Attack the cause, not the effect.
This is what I use...
