Product description
Stop taking apart half your engine just to reach one bolt. The Offset Extension Wrench is engineered specifically for mechanics and DIY enthusiasts who constantly battle with restricted clearances. Featuring a 15.4-inch reach and an ultra-thin 0.63-inch profile, this tool acts as an extension of your own hands, sliding into gaps where traditional ratchets cannot swing. How it works: A robust internal chain-drive system ensures a true zero-degree swing arc. You attach your socket to one end and your ratchet or impact driver to the other. The rotational force is transferred smoothly, allowing you to loosen or tighten fasteners from a comfortable distance. Important Usage Note: This tool is a lifesaver for tight spaces, but it is not a breaker bar. It is impact-ready up to 53 ft-lbs of torque. To ensure a long lifespan, do not use it to break loose heavily rusted or seized bolts. Includes 1/4", 3/8", and 1/2" drive adapters to fit your existing socket sets.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
