Once I figured out that the vegan options and no-carb options are the ones that work for me, I've been quite impressed with the products! I sweat like a pig and have a lot of trouble finding deodorants (and previously antipersperants) that work for more than a few hours. While the first few days were figuring out which options worked and such, and I did sweat more than with the previous antipersperants, the sweating has reduced, and I tested out the No Pong guarantee by delibrately not showering until the following day after a particularly sweaty session of lawn mowing (the sheets were going to be washed the following day), and WOW. Just WOW. I didn't stink! No Pong was recommended by a friend, and I am now a convert.
