Check-Line by Electromatic - ETW Pro Digital Torque Wrench. Discontinued model. Likely was only used one time. This was given to my son by a friend who was moving and cleaning out a bunch of stuff he no longer needed. It comes with the instruction book & plastic tube/container and charging cord (USB). If you have questions please ask - I do not know much about this but I can ask the person I got it from.
