This touch pen fully charges in about 15 minutes. At 7 inches long, that's longer than most touch pens. The fine tip allows it to be more precise than most, for example when drawing. However, subtlety has the disadvantage that even with an electric charge, sometimes a quick touch is not enough and you often have to hold the tip or repeat the touch. I've had two of these pens for about 2 months now and they work just as well as they did when new.
