The Exer-Genie hub and shaft Assembly is warranted from defects for 5 years. We’ll repair or replace it postage prepaid. We have units that have been in use for 40+ years depending upon care. The unit gets hot under heavy use and that’s why we recommend several in a Team situation.
The casing is of a high temperature resistant plastic yet will show signs of wear and tear because of handling and from the heat from the shaft and hub. This doesn’t affect operation it’s more cosmetic wear just like any other training tool.
