    • Quality product. VERY useful, and not common, torque range
Style: Wrench
It's easy to find wrenches with low max torque range or high max torque range. But "somewhere in between" was way more difficult than I thought? For me, the range of this wrench ACCURATELY provides meant I didn't have to buy TWO different wrenches ... nice! I have a 20-150 ft-lb wrench for larger stuff, but for small-mid size fasteners (as typically found on cars and motorcycles) I wanted a wrench ACCURATE at the lower end of the torque spectrum which the 20-100+ ft-lb wrenches are NOT (read those calibration specs carefully, they all have caveats about their accuracy at the lower end of their range!) Using the larger wrenches at the low end of their range (unless you have a high-end expensive model) is inviting disaster on smaller critical fasteners. So not worth it for me. This wrench came with a calibration certification with my wrench's serial number on it and accuracy was more than acceptable for my use. It comes with a nice sturdy plastic case. Requires 4 AAA batteries which didn't come with it. Has a couple of neat features I may or may not use like "Trace"mode" which shows real-time torque as you tighten. It's constructed, feels and handles like a top quality tool. How long it lasts and remains trouble free electronically remains to be seen ... but for now 5 stars. ... show more

    • Pretty cool, does it hold up?
Style: Wrench
Looks nice. I’m going to try it out for awhile, see what I think, with the expectation of getting a full set. I do mobile auto repair work, I use torque wrenches on everything. I am attracted to the precision they offer, and the easy conversion to metric, which is kind of a problem with analogue models. My concern is whether it can tolerate sitting in a van all summer. I’m using lithium batteries to avoid leakage, but in my experience, the rubber hits the road with electronics under these conditions, only quality stuff holds up. The first unit I received the power button was inoperative. I received a replacement in two days. Looking forward to using it, I hope it works out. ... show more

    • Money well spent.
Style: Wrench
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

    • Very Satisfied ---- read on!

I am not an every day user but needed a Torque wrench for the lower scale... in Ft. lbs. this does the trick. I did some research and only used it a couple times. The case it came in is durable and does the job. The wrench was easy to use and since i'm not an every day user, I removed the batteries so they don't accidently go bad in the wrench. Always use fresh batteries! It worked well so far. ... show more
