Just used this set to replace my truck's oxygen sensors and here's the real talk:

The Good: The offset sockets are LIFE-SAVERS for tight spaces. That extra leverage makes breaking loose stubborn sensors way easier than with regular wrenches. The wire slots are actually wide enough to fit harness wires without butchering them - huge upgrade from my old set.

The Okay: Yeah, they arrived swimming in oil like they took a bath in it. Weird finish too - not the smooth chrome I expected. More like they forgot the polishing step. Doesn't affect function but feels cheap in hand.

The Bad: Heads up about the low-profile socket - it's dangerously loose! Measured mine and it's way off spec. Would definitely round off a rusty sensor. Duratech usually makes solid stuff so this was disappointing.

Verdict: For occasional DIY use, it's decent value despite flaws. Just inspect each socket carefully before use and maybe keep your old faithful wrench as backup for stubborn jobs.
