    • Best torque tool I've used
For people complaining it doesn't take the correct batteries-- well you opened the wrong compartment. The batteries go into the end of the handle, not behind the display. If you received a "‎Durofix" tool instead, it is indeed the same tool, because the ACDelco's are made by this company and rebranded. Anyway, I've used this tool for my spark plug replacement job and it worked great. It seems to be very accurate. The only complaint is that I wish it had a lit screen because in tight jobs you may have the tool in areas where you can't look at it straight on and there's not a lot of light. ... show more

    • My Absolute Favorite!
I own several high quality torque wrenches because I'm a stickler for accuracy. I finally broke down and bought this for torquing sensitive parts on my motorcycle because of the low range accuracy. I had no idea how easy this thing would be to use! It is even easier than the ACDelco Torque Adapter I love to use. If you really have to be certain of low torque values, this is the Very Best torque wrench I have ever used and I Highly Recommend it! ... show more

Screen is clear, loud notification, like that I can switch between ft lbs and inch lbs.

    • Money well spent.
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. ... show more

    • Quality for a reasonable price
Nice tool it is loud enough to hear in a shop and when you can’t see the Screen. Easy to set and having the ability to change from Nm to inlbs is nice. I would recommend this tool. I am very satisfied with this digital torque wrench at a very reasonable price

    • Works great for low-torque applications
Bought this to do a Mini Split install. I needed 11-13 ft/lbs for the 1/4” line flare nut and could not find an accurate mechanical torque wrench that was accurate at low torque. The Harbor Freight 3/8” torque wrench claims to work down to 10 ft/lbs, but isn’t accurate (applies way too much torque). Most 3/8” torque wrenches start at 20 ft/lb. This wrench is a little tricky to program (don’t throw away the user guide) but once I got the hang of it I was okay. One other note - if you’re using a Crows Foot wrench (not a socket), and you are holding the torque wrench straight up and down, you should use the Crows Foot at a right-angle (at either 3 O’clock or 9 O’clock position if you imagine the head of the torque wrench is a clock face). It’s tempting to put the Crows Foot facing straight away from the end of the torque wrench (12 o’clock position) but then you have increased the length of the wrench and will not be applying accurate torque. I don’t quite understand the physics behind it, but figured I’d pass it along because it was a mistake I almost made. YouTube has videos explaining it better than I can. ... show more

No certificate nor manual.
