For quite an inexpensive price, this deodorant(regular/unscented)seems to keep a 200lb guy clean smelling throughout a rigorous workout for a couple of hours, without paying the name brand price for almost the same results.

Personally my boyfriend used to use this product, and it did not help him when he sweat a lot. It only lasts for one hour, and leaves white residue.

I love it when I sweat. I love to run with it on. It keeps me Ultra Dry. When I use it it doesn't wear off until I get home. I really like it because it's cheap.

I'm a big fan of regular Ban. Specifically the "Powder Fresh" kind. The smell is decent without being overpowering, and it keeps me from sweating. My only complaint is that if I'm not careful when I put on a dark shirt, the Ban can mess it up with white streaks. So since I like Ban, I also like Ban Ultra Dry, but the two don't seem all that different to me. Regular Ban keeps me from sweating, so why pay more for Ultra Dry?
