Finally, a real pen, really accurate. It has a very nice and simple design. Its weight makes it a good grip. The tip is protected by a screw cap screwable on the opposite end in use. The pen truly has the look of a real pen with a fine tip, which relies on a small plastic disc that protects your screen from scratches and ensures the smooth flow of the line. The line is thinner than a rubber tipped stylus but still keeps a thickness of 2-3 mm (thickness then reduced by the application options used). Great for drawing and making manual notes. The gain in precision is not the time because you have to position the small disk (so not ideal for use with a keyboard) The use of "clip" is obscure and any record or photograph is explains their use. One star less for the price that should be halved.
