I have been using Degree since it first came out, and I will not buy other brands.
Once or twice I tried Suave and Dove as well as a few others to save a little bit of money. They didn't work as well, and I ended up tossing them and buying another stick of Degree anyway. It isn't like it is all that expensive in the first place, so I would have saved maybe 40-50 cents using something inferior.
I apply this once a day, even on extremely hot days. Last summer my air conditioner went out, and I was in 90 degree heat with no relief for almost a week. No matter how much I perspired, this stuff kicked in and took it. I could smell the scent of the Degree off and on, but I didn't smell stinky pits- ever.
Thankfully I have a working air unit and don't have to go through that again, but I still use my Degree year-round. I even buy the "girl" versions for my pre-teen daughter because kids in this age group can be pretty stinky, and I wanted her to have the best protection possible. They have enough to worry about at this age without adding BO to the mix.
