Overall I am very happy with this grinder and would recommend it. In contrast to others; The cord is long enough that you don't need an extension cord for most applications. Dust binding with the included bag is impressive. My previous experience with this type of grinder had me expecting a lot more chaos, this one was about half. It is comfortable and ergonomic to hold for a person with large hands, and the speed control offers a wide range. My only complaint is that the power button could have been bigger, it can feel hard to find and press, especially when it's off. As you can see from the picture it's just a fairly small, regular toggle switch covered in rubber.
