I like comparison tools because  they give the consumer a look at the other products. But, you need to be mindful that some of the sites that use them are those sites selling something and they may have a bias. There is a site for comparing the products that promise a safe colon cleanse that uses the effectiveness, company information, customer feedback and value factors to rate or review the products. It does give the days it took to work and price so it’s worth checking these products if you are in the market for this type of product. Me? Having a colonoscopy at age 50 was enough.
