Rated 5 out of 5 by from It is what they claim it to be! I bought it a couple weeks ago at Menards and I never regret, It is compact and powerful tool, It became so hand when I worked on the brakes of Honda CRV and Toyota 4 Runner. Yes, it did take the lug nuts off a Honda CRV, Toyota Highlander, and Toyota 4 Runner and I was happy with that. I am not sure about the big Trucks such as Dodge Rum, Silverando, and others. Sometimes the shorter sockets will be harder to pull out I hope Rockwell addresses that issue.

Rated 5 out of 5 by from Skeptical but made me a believer! Bought it to change out lug nuts, loosen rusted nuts and parts. Used it to remove lug nuts without a problem. Used it to loosen rusted brake bolts. Did the job and i didn't have to struggle with. Very lightweight compared to dewalts or bosch that i've used in the past.

Rated 5 out of 5 by from It's a horse! Just got it, and the first job was to rotate my tires on my new Subaru. Ordered a set of coated impact sockets and the wrench had the job done in no time. A conversion chart says this thing is capable of up to 212 ft/lbs.....just not on my lug nuts.

Rated 5 out of 5 by from compact and powerful I purchased this mainly to remove lug nuts on my vehicles,removed two tires and did another small job,still haven't needed to recharge the battery.I 've used this to replace an electric impact tool which was a lot heavier, larger and not as powerful.
