I also received the sample, tried it and liked it, then bought the full size. I like it very much! It doesn't have an odor to me, neither when I first apply it or later on. I develops into a very nice color on my light/medium cool toned skin and gradually fades after several days.
I did have a bit of a learning curve in learning how to use it. I first exfoliate in my bath with my Salux cloth. The first time I used it I moisturized first with my Beekman body cream, which was too heavy to put the serum over it. The next time I used a lighter lotion, and the serum went on perfectly. I then used my Beekman the following day.
I have been happier with this self tanner than I have any others in the many years of trying them!
