Let me start by saying these torque extensions are a game-changer for anyone who regularly works on cars. The color-coded design makes it super easy to grab the right one without squinting at tiny engravings.

I used the 100 ft/lb stick for my truck's lug nuts and was pleasantly surprised when my torque wrench confirmed it was spot-on. No more hunching over each wheel with a wrench - just zip them on and know you're in the safe range. The time savings alone make these worth it.

The packaging is classic Craftsman - that sturdy plastic case we all know and love. It keeps everything organized in your toolbox, though I did notice mine says 'Made in Taiwan' despite some reviews claiming USA origin.

Now for the not-so-great part: The 140 ft/lb stick gave me serious accuracy issues. When testing against my certified torque wrench, it was tightening way beyond spec (like 25% over!). That's enough to potentially damage bolts if you're not careful.

Bottom line? For most common torque applications (especially lug nuts), these work beautifully and save tons of time. But for critical applications where precise torque matters, I'd still follow up with a proper torque wrench to be safe.
