abunda_amazon_reviews Watch my video. It's unbelievable that nobody else mentions the fact that this wrench alerts you AFTER you have passed your set value. The manual clearly states "1. When you are reaching 90% of the target torque value, an intermittent buzzer will start to warn you." and then "2. When the target torque value is reached, a high frequency buzzer will warn you not to pull further." Neither of these statements appear to be true. Watch the video I posted. I set the wrench to 13 ft lbs and then tighten a bolt. It starts beeping at over 14 ft lbs and then goes to a solid tone at 15.7 ft lbs. People tell me: "the difference between 13 ft lbs and 15 ft lbs is almost nothing" and they also say "just watch the display while you are wrenching". Sure both of those things are true, but why bother even having a beep setting if you have to watch the display? Why bother with a torque setting at all if the wrench is going to ignore it and beep at some unknown value past your setting? Due to a shipping issue I ended up with 2 of these wrenches. I went ahead and opened up the other box and tried the 2nd wrench. SAME BEHAVIOR.;;Reviewed in the United States on August 2, 2019;;2.0 out of 5 stars;;Alerts you AFTER you pass your set torque value.;;Dankgus;;;I originally wrote this review after owning the wrench for about a month and using it on one major project. Now after a year and more uses, I'm adding additional observations and adjusting my rating from 5 to 4 stars. It's still a good buy IMO, but see below for the full details and things you should be aware of when buying this torque wrench. It's a bit pricey, but this torque wrench is perfect for smaller and more precise jobs. It's far more accurate at lower torques than the craftsman, and easier to use, and to make sure you're torquing everything down right. Digital tone rather than physical click when reaching the set torque, and works on both left and right handed threads, unlike the craftsman. Also unlike the craftsman, this wrench uses AAA batteries which are cheap and easy to replace, and even includes a nice storage case with a slot to keep a spare set of batteries. It toggles easily between Ft Lbs and Newton-Meters on the digital display, sounds a warning beep when getting close to the torque setting, and actively displays the torque readout while you wrench on it. After a day of use, it started displaying the message 'Err' on the LCD when first powered on, but it goes away after a second and still works as normal. I don't know what that's about, but figured worth mentioning. The only other problem I've had with this is that the automatic shut-off timer is relatively short--maybe a minute. That means if you put it down between bolts or take too long wrenching on a bolt to finger-tight before you start applying enough torque to get a reading, it might shut off on you and need to be turned back on. It's a minor annoyance, but you should always make sure it's still on immediately before starting to apply measurable torque if you're not able to read the screen during, or you might miss the important beep if it's not. It only goes up to about 34 NM (25 ft-lbs), so for anything above that you'll want a heavy mechanical torque wrench. This is a very good low to medium-low torque wrench though for the jobs requiring a softer touch like engine work, and fills in the gap below the heavy torque wrenches nicely. The minimum settable torque is 5 NM (3.7 ft-lbs), and while you can still read the display counting up from ~1 NM before reaching that value, I would not trust it for anything lower than that. In fact, I probably wouldn't trust it for anything lower than 7 or so NM (5.2 ft-lbs), as I've had bad experiences so far with trying to use it on ultra low torque jobs like plastic brackets where it seemed to distend the plastic before reaching the specified torque values (in the range of 4-4.5 NM), so to be safe I would say use a finer tool for anything very low in torque value, since the size and heft of this tool, combined with a potentially lower accuracy at the low end of its spectrum mean it could be easy to damage or strip things that require an exceptionally deft touch, so in those cases you may want an even smaller, more precise wrench for the low end stuff, and delegate this to the middle jobs. Between this lack of trust at the lowest torque levels and the turns-itself-off-too-soon issue, I'm knocking it one star upon this re-review, but it's still an excellent buy and worth the money IMO.;;Reviewed in the United States on October 30, 2013;;4.0 out of 5 stars;;Money well spent.;;EZ;;;Works intermittently. Battery holder is loose and has been from day 1. It worked for a while with a nickel stuck behind the battery pack to tighten it against the contacts, but now it just turns off every time it's in a vertical position. An intermittent electronic torque wrench is a very bad thing, It doesn't have mechanical stop like a click wrench - it uses a beeping to indicate torque is reached - so when it has randfomly turned off (i.e. every time the darn thing is vertical), you end up overtorquing the bolts.;;Reviewed in the United States on September 28, 2017;;1.0 out of 5 stars;;Works Intermittently;;DD North Carolina;;;This is a quality torque wrench for professional use. Very trustworthy brand and surprisingly compact torque wrench. This wrench works great and has a nice audio feature to beep as you get closer to your target torque setting. It adjusts digitally from pounds to inches and has many different modes. Batteries are required (4xAAA) This wrench is sure to last many years thanks to the strong mechanic case it comes in. This is for light engine assembly and maintenance. For bigger jobs be sure to purchase the 1/2" version. There are not any length adjustments on this wrench and I am glad it does not have any. It is a solid tool and has a heavy feel and nice grip. Precision tool instructions with calibration data is included so you will have peice of mind that it is VERY accurate. I'm using this tool for maintenance such as spark plugs installation, rear differential, transmission, valve covers, etc. For cylinder head torquing and bigger jobs this wrench isn't designed for that. It has a Max torque setting in the 30 pound range. This is great although it has less uses than the bigger model, it is more precise for bolts requiring LESS torque. Mine came with a tested accuracy of +/- 1.2%! Wow. That's better than a lot of more expensive (tool truck) wrenches I own. The only con is the display can be hard to read at angles and the auto-off feature tends to turn the tool off prematurely. This is a must buy for professional mechanics and knowledgeable car owners alike. Will stand up to everyday/all day use. Great tool! You can't get a better torque wrench for the price and it is a much better precision tool than old click type wrenches.;;Reviewed in the United States on February 14, 2020;;5.0 out of 5 stars;;Works great! Nice medium/compact sized precision torque wrench;;LSX°TRUCKER
