Stinky!
This product smells like rotten egg.  I also did not get it to work the first two times and realized I had to leave the product on for 15-20 minutes compared to the 5-10 listed.  Four star because it works.  Use a paper towel or rag to wipe hair clear.  The silly spatula plastic thing included was worthless.  I eventually used my fingers to apply product.
