The 90-Day Result-Conditioned Money-Back Guarantee, explained
Why we tie our guarantee to a measured result, what happens in those 90 days, and why the product itself is rated for 25+ years.

Energy-saving products have earned some scepticism. Our answer is simple: agree the result up front, measure it on your meters, and give the money back if it is not met.
Baseline → installation → 90 days of measurement → result.
How it works
- Baseline first. The 5-step diagnostic measures your HF noise, temperatures, power quality and energy use against production.
- Agree the result. Based on the diagnostic, we agree the target and how it will be measured (IPMVP Option B or C).
- Install. Clip-on, zero rewiring, during a maintenance window.
- Measure for 90 days under normalised conditions.
- Result. If the agreed result is not achieved within 90 days, you get your money back.
Why 90 days?
Long enough to see a real trend across production cycles; short enough that you are not left waiting. For seasonal sites we recommend continuing to measure for 12 months — but the guarantee decision is made at 90 days.
And after that?
The Black laser-engraved Denka® Platinum Plate is rated for 25+ years of service: no consumables, no moving parts, chemically stable ceramic.
