I bought this brand a month or so ago, but didn't know how to use it, but now after reading several posts here on 505 brand, I'm wondering if I should go exchange this. I haven't opened it. Of only a few reviews on Joann's website most were thumbs down mainly regarding the smell. I know those types of reviews are absolutely opinion, and not fact-based because smell is such a personal thing. Whether or not the product works is another facet altogether.
