“If any element of the Evidence Loop fails to perform as described, return it for a full refund.”
For: Guarantees the product works (the buffer locks, contacts are alerted, GPS streams) — not an outcome. Honest, on-brand for a device about accountability, easy to stand behind.
Watch: Requires the device to reliably do what's claimed at PoC/MVP — only promise once the basics are tested.
“Try ProofGuard for 30 days. Not for you? Return it for a full refund.”
For: Removes purchase risk, standard for new consumer hardware, only modestly beyond the legal baseline (below). Easy to communicate.
Watch: Return logistics + condition terms on a physical device. Pick a window you can actually honour.
“12-month warranty against manufacturing defects.”
For: Expected for electronics, cheap to offer, reassuring. Pairs with either option above.
Watch: Define defect vs misuse; needs a repair/replace process.
e.g. “guaranteed to get you believed / hold up in court”
For: Tempting — it's the emotional core of the pitch.
Watch: Do NOT promise outcomes you can't control (whether someone is believed, whether a file is admissible). Legal liability + impossible to honour. The copy should say the record exists and is yours to provide — never that it guarantees a result.
Online sales already carry a 14-day right to cancel (Consumer Contracts Regulations), and goods must be as described / fit for purpose / of satisfactory quality (Consumer Rights Act 2015). Any guarantee you advertise sits on top of these — so a 30-day money-back is only ~16 days beyond what's already required. Not legal advice; confirm wording before publishing.
