The brand states two numbers that do not line up: a 60-day money-back guarantee and a 90 to 180 day timeline for results.
If you judge HoneyFil only within the guarantee, you judge it before the brand's own suggested minimum. If you wait for 90 days or more, the guarantee will have ended.
The page acknowledges this repeatedly, which is to its credit, and our post on the gap works through the math.
Decide in advance what a good sign at day 60 would be, such as easier routine or steadier afternoons. Keep a log from the start, and make the continue-or-refund decision before day 60. If you continue, do so knowing the refund option has ended.
