Milwaukee 1/2" Impact One Key

Wondering if the "One Key" feature on model # 2863-20 is worth the extra $63.00? Do you have this feature and would you purchase it or just get the base model # 2767-20 for $197.00 ? This is bare tool price I have charger and Batteries. Don't mind paying the extra for the programmable torque settings if they work. #GeneralToolDiscussion
