What is best bp cuff to have for home use? arm or wrist? digital or regular? thin arms, 92 and 115 lb. thanks.

Digital, arm cuff: Arm cuff is usually more accurate than wrist cuff. Digital is easier to use because one does not have to listen to anything nor watch the dial drop down. Instead, one just pushes the button and waits for an answer. At 115 pounds, an adult cuff is used unless the arm is super thin. If super thin, one can try a child cuff, but it will give a higher reading (and is hard to find at any stores).
