Plastic housing cracked under 125ftlbs of torque.

The torque driver works well but if you are going to rely on the buzzer to let you know when you’re within the correct torque then you need be in a very quiet area cause you can’t hear it if another noise is around. The other thing people should know is the battery cover is secured by a small screw which threads onto the body of the torque driver which is plastic so I don’t know how many time before the thread gives up and the screw will just falls off.

Very accurate tool. Reads spot on with the Snap On wrenches we have at work. Nice range as well.

Received on time. Thanks, Amazon. Tool is well packaged and looks nice although the plastic housing might not survive a drop on the concrete floor of my garage. It is easy to use and seems to provide reliable readings. Began a project to recalibrate my torque wrenches using this tester. Naturally this required repeated tests of torque adjustments on the wrenches. The project was lengthy. I noticed the battery level (shown on the tester screen) beginning to drop off after only about 5 minutes of use. Hmmm . . . Within an hour the battery level was very low and tester began to react abnormally. After about 90- minutes of use, I removed the original battery and put in a new one. Got the same performance. Totally unacceptable. Processed a return and sent it back to the Amazon barn.

You can tell the moment you open it how much care and time went into making this product. The adapter is pure quality and I found it to work great for my homeowner needs, mainly motorcycle stuff.

Started acting up, can't return (past date) extended warranty no help. Can't get help from seller.

Overall very well executed product, starting with the metal box that conveniently holds the torque adapter, instructions, battery, and even a little screwdriver for opening the battery compartment. Using the torque adapter is simple and easy: turn it on, use the up/down keys to select desired torque, and choose your mode: “F” mode displays current applied torque and “K” mode displays peak torque. Then it's just a matter of tightening until the torque adapter alerts you to stop by which it has three methods: 1) the screen shows you current/peak torque numbers; 2) there's an audible intermittent beep that starts as you approach desired torque and turns into a solid beep when you hit it; 3) there's a green light indicator (and a red light when you go too far!). I will point out that this model of digital torque adapter doesn't feature an angle measurement – so be aware of that if you're looking for that feature. Other features this model does have are: a backlit screen, selectable units (lb/ft, Nm, Kg/cm, lb/in), battery indicator, and a memory function for easy recalling of frequent torque values.
