Purchase with warranty




The ability to defend yourself from non-functioning and damaged equipment due to unforeseen incidents. Protection from accidental damage to your MDF® Instrument, covering repair or replacement for the extended warranty period.

What is M+Unity™?

M+Unity™ is a 2-Year extended warranty for complete coverage of your MDF Instrument to include accidental damage that is not covered under the Lifetime Warranty. M+Unity™ is purchased in addition to the instrument and will cover the repair or replacement of that instrument from events such as mistreatment, liquid or chemical exposure, impact or exposure to extreme conditions.

What is not covered?

M+Unity™ is full coverage against damages that inhibit the performance of your instrument.  The coverage does not include normal wear and tear that does not affect the functionality, or aesthetic issues related to the appearance of the instrument, such as pen mark, and dye transfer from uniforms or bags. M+Unity™ does not include items that are lost or stolen.
