Importantly, Clarity X and its sister product Focus X were extremely ineffective for me. Following the instructions on the bottle led to no noticeable change for me over the full trial period.
Secondly, the product might not be outright fraud, but its business practices are unethical. You can quickly and easily buy $10 of the sample, but you are then charged $85 per month, and they do not inform you of this anywhere but the fine print (or on this website, if you did your due diligence unlike me). You don't have an account with them, so it can be very difficult to even know you have an open subscription.
When trying to cancel the subscription, the salesperson/customer service rep will try every trick in the book to try to get you to stay, even offering a 60% discount. Bottom line is that these pills won't do anything for you and you must be wary about their charges.
Bottom Line: No, I would not recommend this to a friend
