it works.


The tire shop personnel tends to over-torque lug nuts with an impact wrench, often exceeding the specified torque. Breaking them loose in case of a flat can be nearly impossible. I purchased this tool in March 2019, after struggling to break them loose during a tire change. It's now December 2020, and thankfully, I haven't had to change a tire until now. My wife got a flat, and when I tried the old way with my four-way lug wrench, it didn't work. I used this tool and had all five lug nuts loose in about two minutes, with no swearing, straining, stress, or hassle. I changed the tire quickly and headed home. Surprisingly, on the way home, I had a flat tire on my one-ton truck. Again, the four-way didn't work, but this tool had all eight lug nuts loose in maybe two minutes. It works quickly and effortlessly. One caution: the tool's makers advise only using it to loosen lug nuts, not to tighten them, as it significantly amplifies torque and may lead to snapping or pulling out the lugs with minimal effort.


Initially, it feels awkward to use – as if it might bind on the nut. However, this is more of a sensation than an actual issue. After a few uses, positioning it correctly on both wheel nuts becomes second nature, and it works effortlessly. It easily cracked the overtightened nuts on my SUV. When re-tightening, caution is needed as it can easily over-tighten. It's advisable to disassemble the unit and re-grease the gears, as there's minimal grease applied from the factory.


Compact and lighter compared to the majority of others, ideal for use in the wife's car.
