KAIFNT K552 Digital Torque Adapter, 3/8-Inch 5 to 100 ft·lbs, Buzzer/LED Flash Notification, Dual Direction

good

The toque adapter is so nice and accurate I done my Ls engine project with and worked perfectly

I bought this torque adapter the special Black Friday pricing due to it being compact and easy to carry around, overall I am happy with it at a price of under $50 as I also have a couple of good full size torque wrenches, it seems to read comparable to them in my limited testing, it is certainly lighter and smaller, which is the main reason I bought it, I just wish its carrying case was a bit more compact.Now the good and the bad, I like the display with the color coded LED's, and progressive beeping as you approach the torque set point.The Good points, it seems to work over a wide range of torque values, there was a also an included calibration test sheet (though some lines are blank, like testing date, and signature), the display is reasonably intuitive, there is also a set of spare batteries included, with one set in the adapter with, with a pull to activate plastic tab, as well as a spare set in the carrying case. There is even a small screw driver included used to open the battery compartment There are also step up / down adapters allowing it to be used with 1/2 or 3/4 inch sockets, and step down wrench adapter letting it be used with 1/2 or 3/8 wrench handles.Now the Bad, As mentioned above the carrying case is somewhat large having space for those adapters, spare batteries, etc., overall function is good, but has one BIG flaw it powers off after 60 seconds of inactivity, which can often be too short of time to get wrenches in position in awkward spots. Also one of the included batteries was inserted backwards, which I caught right away, but could have been a big headache to spot if I had not been paying close attention when I pulled the pull to activate plastic tab. Also like many tools the instruction sheet is minimal, and written in poor English, though it is better than many I have seen.If the power down timer had been just a bit longer say 120-180 seconds I could see giving it 5 stars, but 60 seconds is just too short of time.The bad points,

First of all I am not sure how they think anyone can get away with selling a product that shows different specs and then have no Made in [country] stated which last I recall is Illegal.It just says ray jay ltd which is nice since it's based in Taiwan but I don't speak Taiwanese.So maybe I can ask my support question here:1. Why does the manual pictured not the same as the product spec?If I destroy my engine because it can't read under 50lf lb in the manual unlike the product description which says 12ft lb-250 when installing spark plugs who do I call do reimburse me for a destroyed engine? Thanks.*edit update*Hate to leave one star as I tested it but still not sure of it's accuracy from 12-20 ftlb as the manual said it wasn't specced for this. Some kind of warranty info and support email would be nice?

This is a great torque driver offering a wide torque range. The digital screen will show torques below the 5 in-lbs. minimum so hopefully that will answer some questions and it was spot-on accurate when compared with another torque driver I had.I decided to return this, however, because I found myself reaching for another torque driver that featured a T bar. Trying to torque something higher than 45 in-lbs. is really difficult with this without fear of damaging the digital screen when using as grip leverage.Overall I'd recommend as a value-priced digital torque driver, but I didn't need another one in my tool bag at this time.
