Risk-free appears in the framing. So does a more candid mention of the catch.
Risk-free is marketing shorthand for a money-back guarantee. The catch language is the page's own admission that the guarantee is shorter than the suggested timeline, which means you may need to decide before you have given it a full trial.
Both statements come from the same page, and they pull in opposite directions.
A guarantee reduces risk but does not remove it: you can still lose time, shipping costs or a refund you fail to claim in time. Read the refund policy for conditions, track your purchase date and request in writing. Treat risk-free as something you have to earn by following the process.
