I really don't like scented products. I have been using the Whole Foods 365 store brand unscented foaming soap; I like it, but I don't want the packaging and I wanted a product that comes without all the water, i.e., I wanted something in a tablet form. This is the first unscented tablet I was able to find! It has even less scent than the 365 (which smells mildly of chemicals), and works great.
Cons: I do think it might be slightly more drying to the skin. Also, I am not sure why it needs to come in a tub (it could come in a wax paper bag and be even more eco-conscious).
