Return, Exchange , and Warranty Policy

The Biosense® Breath Ketone Monitor is intended as a single-user medical device (Class 1). We do not refund the cost of returned devices due to sanitation reasons; all sales are final.

BIOSENSE® comes with a 1-year limited warranty.  The warranty covers defects or malfunctions in your new BIOSENSE®. This warranty is valid for one year from time of shipment, and coverage terminates if you sell or otherwise transfer the device.

Readout Health will replace any defective or malfunctioning part at no charge within the warranty period. You will be responsible for any shipping fees.  Any issue that is caused by abuse, misuse, or an act of God (such as a flood) are not covered. Also, consequential and incidental damages are not recoverable under the Biosense™ warranty.
