Review on KAIFNT K552 Digital Torque Adapter: 3/8-Inch 5 to 100 ft·lbs, Buzzer/LED Flash Notification - Dual Direction by Michael Powell

I love the packaging of this product. The case is well made and contains everything you need to use this adapter as shown in the photo. The instructions are pretty good and easy to use. But is it accurate? I tested this with two fairly new Neiko Pros and a 15 year old Precision Industries torque wrench. Accuracy within 1.5 percent. To my surprise, Precision Instruments accuracy was 10 ft/lbs on all planes. It's easily adjustable and I was able to set it to read + or - 1 ft/lb at all levels. This was and is my wrench so I am very happy that it can be adjusted to this level of accuracy. These tests were clearly at the low end of this adapter's capability from 25 to 250 ft/lbs. At a higher torque load I had nothing to test. Since it was new at the time of testing, I can't comment on durability. But I am very impressed with the quality and accuracy of this adapter. And of course the photos are for illustrative purposes only, so actual torque figures are not shown.
