A digital wrench is absolutely electronic. Take the batteries out and see how well it works for you. I have a nice dial wrench made by Mountz. Some have a secondary fixed hand that will show the torque was achieved when the torque is hit. I do use a couple snap ons for my wheels preset, and stay away from air impacts at plus or minus 20 percent at best. Sturtevant Richmond makes great torque wrenches in my opinion. Go snapping off bolts or damaging parts, it's a costly car repair. You get what you pay for. I don't use red Loctite, only blue if you ever want to remove a part. Some new bolts can be purchased with thread patches already in place. This review owner seems to have done quite well on a 1000 dollar buy. Some spending much more have far greater issues.
Happy motoring.

Click wrenches of any type are operator influenced. In order, rotary transducer with a nice analyzer like a Atlas Copco Acta, beam, dial, and lastly click. You can get a nice dial with an audible indicator with a light. Click wrenches are the worst for repeatability. The operator has to stop at the exact moment it clicks. It may be a 4 percent standard deviation, but it's hard to do so operator to operator. Beam is typically 1 percent. Some check their tools with a fixed transducer on a test joint set up with stacked washers. These simulate a hard or soft joint condition. After reading the review however, no tools were even needed.
