I have tried 6 diffrent colon cleanse products because I wanted to be sure I found the best one. Of the most popular ones, I have found this to be the best. It is manufactured in the usa which makes me feel more comfortable with the ingredients. It has helped me to lose weight, be more regular in the bathroom, and just made me feel more awake overall. It seems to be priced middle of the road. I have found that buying any dirt cheap products is ususally a mistake. I dont want to go name bashing here but you get what you pay for.
