I got this to use on my car for tire changing. At 90 ft lbs, the little lug wrench would not hack it. Setting torque was simple, but noise maker did not. Its hard to read display while trying to torque a wheel. The 4 page manual was written in passable English but too much was put int one sentence to make it fully understandable. after reading the \"manual and watching the video I finally realized after entering the torque setting, one has to hit the {E} key. now it works. The battery cover has a strip of thin white tape over the slot in the cover. One item enclosed is a (disk cutter)removing the tape because it bothered me revealed the slot that the disc cover fits and one unscrews it. Lastly, the video is in Chinese with English sub titles. Twice it mentions twisted rice. Once it mentions beef and rice. Why? beats me. anyway its a substantial tool. Just be prepared to keep rereading the manual and send an email to the company so you get the video. Once it set up, the alarm is loud enough. I used the \"T\" setting. No idea about the others.
