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

New, sealed. excellent
Style: Torque Wrench
New, sealed item. This thing looks like it's going to be very versatile. Going through these instructions and learning how to use the buttons a little bit cumbersome maybe not as obviously intuitively easy as it looks but after I use it a few times I'm sure I'll have it memorized.

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

Better than the price paid
Style: Torque Wrench
This was not as expensive as a lot of others so I wasn't sure what to expect, it has surpassed it all. It is accurate and well made. I havent had any issues with this on anything that I have used it on. I am a garage mechanic so by no means a professional, but it has held up well on the several cars I have used it on. ... show more

It sucks. Don't waste your money.
Style: Torque Wrench
I have 2 of them. They both do this... In order to turn it on, you will have to remove the 2 screws, remove the battery pack, reinstall it - and it turns on. Then you have to use it within 60 seconds or it shuts off and you have to repeat above. Every time I go to use this, I have to recharge the batteries. Because even when there's nothing on the display, it totally drains the batteries, in 10 minutes. I can't get anything done because I have to stop, recharge batteries, or put new ones in. Next, put battery pack in, and try - within 60 second - to crawl under car, get in position, assemble the socket, extension onto the wrench and torque down the drain plug....oops! 61 seconds - turned off! Crawl back out from under the car. Remove the 2 screws and the battery pack. Reinstall the battery pack so it turns on. Try to get back into position within 60 seconds. You see why this is impossible! Waste of money! ... show more
