Refund policy
To protect both our customers and our business from errors and fraudulent claims, all issues involving incorrect, missing, or defective items are handled under the verification process below. Placing an order with Millton™ constitutes acceptance of these terms.
Orders placed for time-sensitive needs are placed at the customer's discretion. Once an order has shipped and tracking shows in-transit or delivered status, refunds, cancellations, and chargebacks based on delivery timing will not be honored.
100% Satisfaction Guarantee
Our product page states: "If you don't feel the difference in how your vehicle runs, send it back for a full refund. No questions. No hassle. You're either 100% satisfied or you don't pay."
This guarantee applies only to single-unit purchases at full price. It does not apply to:
● Any order using a promo code, flash sale, or other discounted pricing
● Free or bonus items included with a promotion
● Lifetime warranty upsells (covered separately under warranty terms)
All bundles, discounted items, promotional purchases, and free gifts are final sale and are not eligible for refunds, returns, or satisfaction claims — except in the case of a verified fulfillment error (see below).
Incorrect or Defective Items
If you receive the wrong product or a unit that arrives physically damaged, contact us within 7 calendar days of confirmed delivery at millton.co/pages/contact.
Claims must include all of the following:
1. A clear photo of the item showing the issue
2. A clear photo of the shipping label on the original packaging
3. A written description of the problem (wrong item, damage, dead LEDs on arrival, etc.)
Incomplete claims will be denied. Once a fulfillment error is verified on our end, we will issue a replacement. Refunds are provided only where a replacement cannot be fulfilled. Returns are not required unless specifically requested.
Missing Items
Notify us within 7 calendar days of confirmed delivery. Missing-item claims are verified against shipping weight, fulfillment records, and carrier data. Where verified, we will ship a replacement or confirm the item was dispatched separately (bundle orders may arrive in multiple packages). Claims that cannot be verified internally will be denied.
Vehicle Compatibility
FullFire™ is built for GM V6/V8 vehicles with AFM or DFM systems (2004–2024). The full list of 80+ supported models — across Chevrolet, GMC, Cadillac, Buick, Pontiac, Holden, Saab, Saturn, Isuzu, and Suzuki is on the product page.
Refunds and returns are not offered for:
● Vehicles outside our compatibility chart
● Vehicles where AFM/DFM has been previously deleted via mechanical kit, tune, or other modification
● Customer error in confirming compatibility before purchase
● Change of mind
Unsure about your vehicle? Contact us with your year and model before ordering. We confirm compatibility free of charge.
Product Performance
The Millton FullFire™ AFM Disabler is a plug-and-play OBD-II device that locks your GM engine in full-cylinder mode. It does not modify your ECU and is fully reversible by unplugging.
Refunds and returns are not offered for:
● Subjective performance expectations
● Fuel economy changes (disabling cylinder deactivation typically results in a 0–0.5 MPG difference)
● Battery drain caused by leaving the device plugged in during extended parking (unplug if the vehicle will sit for 2+ days)
● Pre-existing engine damage, lifter failure, or mechanical issues predating installation
● Dissatisfaction with exhaust note, throttle response, or drivability
If your unit fails after a period of normal use, contact us regarding replacement under the satisfaction guarantee (single-unit full-price purchases) or lifetime warranty (if purchased as an upsell).
Shipping & Delivery
All orders ship free. Delivery estimates are not guaranteed, and Millton is not responsible for carrier delays, weather, customs holds, or other events outside our control. Orders cannot be cancelled once shipped; refunds and chargebacks will not be issued for packages tracked as in-transit or delivered.
Abuse, Fraud & Chargebacks
We reserve the right to deny any claim that:
● Shows signs of misuse, abuse, or fraud
● Contains inconsistent or misleading information
● Is filed outside the 7-day verification window
● Lacks required photos or documentation
● Conflicts with carrier, shipping-weight, or fulfillment records
Customers who file a chargeback before contacting us, or in violation of this policy, may have their claim permanently denied. All correspondence, tracking, shipping-weight data, and fulfillment records are retained and submitted as evidence in chargeback disputes.
Final Determination
All resolutions are made at our sole discretion based on available verification and carrier data. Our decision is final.
