Fails miserably as a writing instrument.The problem is simply that the stylus is as wide as a fat pencil eraser, and about as sticky. It does not glide across a capacitive tablet screen, it sticks. It's also not tremendously sensitive, so 'swipes' typically get dropped mid-stroke. In essence, it depends what you're expecting to use it for. For basic navigation of the OS, it works. Essentially, screen taps. Even dragging things is not tremendously useful. I bought this, and a variety of other styluses, to take handwritten notes during meetings. I have several Android tablets and it simply doesn't work; the thing is too fat and not sensitive enough to suffice as a writing instrument. The problem is not unique to this stylus. For sketching or writing, you need something like the Galaxy Note, or simply a better stylus (which I haven't found yet). Here's where old resistive technology was superior to capacitive: crummy for finger control and multi-touch, but worked with a fine-point plastic stylus.To re-iterate: as a writing instrument, this stylus, as with all I've tried so far, is unusable. If you just want to use it for basic OS navigation and hunt-and-peck typing on the soft keyboard, it will suffice, albeit with some frustration.
