PayPal and other payment processing methods charge non-refundable fees, so we cannot refund these fees in the event that the customer misunderstands the product or how it works.

All sales final- warranty provided for 90 days on all OneGauge components (except those listed below). Warranty does not cover damage due to improper installation or misuse of the product.

Any custom programming or design, when billed hourly, is not refundable under any circumstances.

The OneGauge hub and LCD screen will be programmed according to the original sensors ordered. Should the customer require a reprogram to add or change sensors after the unit is received, a $30 minimum reprogram fee may be charged. Any updates required by OneGauge will be provided at no charge. OBDII setups receive one free code update/screen adjustment (adding/removing sensors only) after purchase in the event that their vehicle’s ECU does not provide all of the sensor readings expected.

For LCD screen purchases, the customer is additionally required to have a micro SD card and an way to transfer files to the SD card in the event an LCD screen refresh is required or requested.
