MDF® instruments have been handcrafted in the MDF® artisan tradition since 1971. They are super-duty, high-performance medical tools that meet the toughest requirements of precision and accuracy. Because of our relentless pursuit of quality, we are able to offer unrivaled warranties. To ensure that your instrument is covered by these warranties, please register it here.
MDF® stethoscopes with defects in material or craftsmanship will be replaced or repaired without charge for the life of the instrument (excluding the Singularis™ line, which has a two-year warranty). This warranty also includes tubing.
Due to limited quantities of each print, limited-edition stethoscopes and stethoscope tubing may not be replaced with the corresponding design or color. Mprints Collection Stethoscope warranty requests will be fulfilled at the discretion of MDF Instruments.
The use of non-authorized third-party modification services is done at your own discretion and will void the Lifetime Warranty MDF Instruments. MDF Instruments does not guarantee that the third party modifications will meet our requirements, be effective, accurate, or reliable.

MDF Instruments reserves the right to refuse credit or refund for items not returnable due to health, sanitary, or consumable component issues. The exclusive remedy for any defective product is limited to the repair or replacement of the defective product. MDF Instruments may elect which remedy or combination of remedies to provide at its sole discretion. MDF Instruments shall have a reasonable time after determining that a defective product exists to repair or replace a defective product.
MDF Instruments’s replacement product under its limited warranty will be manufactured from new and serviceable used parts. MDF Instruments’ warranties apply to repaired or replaced products for the balance of the applicable period of the original warranty, or for ninety days from the date of shipment of a repaired or replaced product, whichever is longer.
MDF Instruments’s entire liability for any defective product shall in no event exceed the purchase price for the defective product. This limitation applies even if MDF Instruments cannot or does not repair or replace any defective product and the exclusive remedy fails its essential purpose. MDF Instruments has no liability for general, consequential, incidental, or special damages. These include lost profits and the cost of the installation or removal of any products, the installation of replacement products, and any inspection, testing, or redesign caused by any defect or by the repair or replacement of products arising from a defect in any product.
If MDF Instruments determines to replacement a product for any reason, including warranties, the replacement product will be sent to the shipping address on the original order or location of purchase. MDF Instruments will not be responsible for shipping costs to replace any item in another location or country other than original purchase location. In the United States, some states do not allow exclusion or limitation of incidental or consequential damages, so the limitations above may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
