Review: Decent Wrench and Torque does go down to 4ft-lbs - So far this has been a great tool. I have used it multiple times now and the controls get easier each time. I really like the feature that logs the max torque, so when you are in an awkward position and you can not see the meter, you can take the wrench off and see how close you are to the actual torque requirement and stop or keep tightening. The wrench says it goes from 4 to 99 ft-lbs, and it does, but there is a catch. If you read some of the other reviews you will see that some are saying that it does not go down to the 4 ft-lbs, and I did experience this when I got it out of the case for the first time. I was pretty bummed and a little T.O'd that the lowest I could set the tool was 10 ft-lbs. It seemed like it was false advertising and was ready to send the tool back, BUT I decided to use the tool and found out that it starts reading at 4 ft-lbs, so you can torque down to 4 ft-lbs, but you just can not set the alarm that low. So I figured that on the occasion when I have a very light torque I could just watch the digital meter. Most wrenches don't go down to 4 ft-lbs so not having an alarm is not a big deal for me. The wrench overall has a sturdy construction and it has a pretty smooth action. There are wrenches that are more and ones that are less and without being able to test them all, I would say that this seems to be worth the money for the quality and range. I really don't know what I could actually gain by purchasing a more expensive wrench, this one does the job.
Review: Reliable high-torque wrench for automotive work - As a hobbyist mechanic who enjoys working on my own cars, I decided to invest in a heavier duty torque wrench for critical engine bolt applications. After researching options, I settled on the ACDelco ARM601-4 and have been very satisfied with its performance. This wrench is built sturdily and has a nice weighted feel to it. The digital display is bright and easy to read. It covers a wide torque range up to 147 ft-lbs, which is plenty powerful for most automotive needs short of heavy equipment. I've used it for torquing lug nuts, axle nuts, engine cylinder bolts, and more. The accuracy is spot on each time. The wrench beeps when you reach the set torque value so you know when to stop. This gives me confidence I'm applying the manufacturer's torque specs correctly. The battery life is excellent, lasting for several months of weekend use between charges. The molded case it comes with is also handy for storage and protection. For anyone working on cars in their own garage, this heavy-duty digital torque wrench is a must-have tool. The ACDelco ARM601-4 provides reliable and accurate high torque capability without breaking the bank. I'm glad I chose it over cheaper wrenches that likely wouldn't last or properly calibrate.

This thing is nice. Perfect for hobbyists and even shop use. This thing will last that’s a guarantee. And it’s less than .5% margin on all torque loads. That’s fantastic.
