It does not have a knob to select grind settings. You can press the button and release for a coarse grind or hold it longer for a fine powder. I use it to grind whole coffee beans for my Keurig reuseable Kcup. It works very well for the price and is attractive sitting out on counter . I like the small size too.
No. There are no settings available. To operate, one depresses a button located on top of the grinder and keeps it depressed until the appropriate fineness is achieved. I have read somewhere (can't remember where - perhaps a review) that it is not suitable for grinding for coffee presses.
