I have only been using this product a week and have been seeing results for days already. The taste isn’t the greatest but definitely wasn’t as bad as I prepared myself for. It was easy to use but made a little bit of a mess . Over all I think this is an excellent product and working great. I will definitely continue using and purchasing this product in the future. I think this product is beyond worth the money, especially compared to having a professional whiting, I recommend you try this first before putting out hundreds of dollars. BUY THIS PRODUCT ITS AMAZING !!
