Rivzman Solutions offers life time warranty, that may vary by the type of instrument, on almost all of its dental instruments under normal use. The warranty is against defects in workmanship, breakage, faulty joint  and corrosion. Rivzman Solutions will be happy to repair or replace any such products. However, expected wear and tear under prolonged use are not considered to be defective, and thus are not covered.  Additionally, modifications of any kind and improper instrument cleaning and care may void the warranty. Please contact us at info@rivzmansolutions.com.au for any question in related to faulty instruments.
