ARM602-4 1/2” (14.8 to 147.6 ft-lbs.) Heavy Duty Digital Torque Adapter with Buzzer and LED Flash Notification – ISO 6789 Standards with Certificate of Calibration

Si funciona correctamente, buen producto.

This ad is innaccuate. The minimum setting for this product is 14.8 ft p or 20nm - Not 4 ft pounds. If you want to get a reading less than 20nm you need another product. However the product itself looks robust and professional.

It's been some time since i used this but all the features work as explained. The only problem is that setting the tool to alarm you when you reach the desired torque is just a bit convoluted. Don't get me wrong, it works perfectly but you must follow directions that are in the manual. If you don't, you're going to know something is amiss before you strip a bolt. There was something about setting the torque that wasn't as straightforward as it seems it should be. If you only use the tool all the time, no problem, you'll have the process down pat. If you use the tool only ocassionally, just make sure you keep that manual stored with the tool and follow the manual each time you use the tool. As for accuracy??? All I can say is I trust this tool much more for ehigh torque value than I trust my old, inexpensive torque wrenches that I have used and become familiar with over 15 years. I tested the tool against my torque wrenches for lower values and they were pretty close. I used this tool on a strongarm bar instead of using a torque wrench. Torque until the alarm goes off. Works great. If I need one of these that is calibrated for higher values, I will buy the same brand.

This is a great device. It is far easier to use than my click style torque wrench because the beeps let me know when I am approaching the correct torque setting. I've used it about fifteen times in the past month, working on both my own and a friends motorcycle. Great device and recommended for do-it-yourself mechanics.

It looks very well made nice and simple to use
