Legal Language
Our multipliers are unconditionally guaranteed against defects in materials and workmanship.
Use with an impact wrench, hammer marks, lever marks, use of a "cheater" and so forth will void this warranty.
If, in our estimation, the device shows evidence of abuse inconsistent with proper use, this will void the warranty.
Each device comes with an in-line torque-limiter which must be used and must not be circumvented.
This in-line torque-limiter must accompany any warranty claims along with the multiplier for our inspection.

We take our quality and our warranty very seriously.
We trust that you take pride in your work (as we do in ours) and will use our device as intended.
