Performance Tool W32139 Extension 3 Piece Review

I got these primarily for tightening our basement wall braces and they work well for that. Little torque (45 ft-lbs) but I didn't notice much flexibility in them for this purpose. They seem pretty straight for what they are and are a decent weight so I'm not really worried about them.

For my current project I needed a 24" extension but after comparing the prices of other two piece single extensions I decided I "need" this one because I never know when I might need a 36". 24" used in my project, checked two other nuts for loosening and re-tightening - these things are solid. I would buy again anytime (if I lose them or they get stolen). I doubt I'll ever bend or break them.

I bought this extension set at a hardware store. I was preparing for a timing belt job and chose this kit to help me get to the engine bay to remove the engine side mounting bolts and harmonic balancer. Some flex in overtime is inevitable, but that was just ridiculous. The engine mounting bolts are torqued to approximately 40 ft-lbs.
