Review on 🔧 FIRSTINFO 3.4:1 Manual Torque Multiplier Wrench - 600 Nm - 1/2 inch Drive - Labor Saving Tool by Todd Markel

First important note: I only used this to tighten the nut to 500 ft/lbs so I didn't drive it to the stated limit. It worked great for me and was incredibly cheaper than a torque wrench with the same capabilities. The multiplier has an accuracy range of around 4%, which must also be taken into account with the accuracy of the torque wrench used. This can result in a relatively large discrepancy in actual torque, but that's the price to pay to save a few hundred dollars (minimum) on a more powerful torque wrench.
