Query: Impressed.

I've been an avid user of Certain Dri PM, and gotten pretty decent results with it. I recently bought this after reading the rave reviews about other users' results, and I must say it works decently well. It does its job, and it doesn't smell bad either. However, I think the deodorant fades somewhat quickly and doesn't last as long as other deodorants I've tried in the past. Good and dependable product overall.
