    • Decent Wrench and Torque does go down to 4ft-lbs
Style: Torque Wrench
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. ... show more

    • Reliable high-torque wrench for automotive work
Style: Torque Wrench
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. ... show more

    • Good tool but instructions are unclear.
Style: Torque Wrench
I bought this to torque the head bolts on a Toyota pickup. It's a nice size (not too long) and it came with a calibration certificate. Ergonomically a good tool. Cons: the controls are a little hard to get used to, setting the torque amount, the mode etc. The instructions did not exactly match the function of the tool. Also there is a battery compartment for AAA which it uses, but there is also one for two CR2032, but the instructions don't mention it at all. And they don't appear to be needed. Overall a good tool, but the instructions are unclear so you have to kind of figure out how to set it on your own. ... show more

    • Great product worked well
Style: Torque Wrench
I purchased this to install cylinder heads on my engine after a head gasket install. I have a mechanical one but wanted the extra assurance that I did get the torque specs as close as possible. Worked great. Comfortable handle and is simple enough to use. I wish the lcd was backlit so you could see the reading in dark areas but that would just be an added luxury I was able to use it fine without. Comes with a durable case as well, very satisfied with the value to price. ... show more

    • Horrible product in all aspects. Had to replace.
Style: Torque Wrench
I have had this wrench for 3 years now. I have no idea how it lasted that long without me launching it. It is just so difficult to do what you actually want a digital torque wrench for. Starting with case, looks good but latches fall off every time you open it, adjusting it is the least intuitive process I have encountered and when using peak hold feature, the wrench beeps at different torque every time. For example, internal engine bolts that needed 28 lb ft , recorded as low as 26 lb ft but multiple times as high as 35 lb ft. I ended up starting again with a regular click type that was calibrated. The final insult is that after limited use over 3 years (as I don’t trust it ), the display over the LCD has fogged and now the numbers are nearly impossible to read. I note today they are selling at 50% off yet still somehow get a high rating. I am sure some folks will say I get what deserved buying a ‘cheap’ product but when I bought it, it was double current price. In short, every aspect about this wrench was unacceptable and I put up with it as I didn’t want to buy another. I finally gave up. Worse part is, I just didn’t trust it. I have replaced it with a click type that had calibrated. Ok, peace out. ... show more

    • Great Wrench!
Style: Torque Wrench
I love the ACDelco Torgque wrench. Great for switching rims! Easy to read the digital meter for torque levels. The wrench is longer than a normal socket wrench. This provides leverage when loosing tight bolts.
