Best weight, length, and tip. This is my favorite stylus by far. I have had quite a few because I have an iPad and an iPhone. Which I move around my house because I take and edit photos. The others are too short, too light, too skinny or skid on the screen. Recently the customer service department sent me a replacement because I ordered incorrectly. Greatly appreciated.
Output:
positive
