Review on Blue Cordless Electric Coffee Bean Grinder With Rechargeable Battery & Removable Stainless Steel Bowl For Espresso, Seeds, Nuts And Spice Grinding by John Hill

This little grinder is great for coffee beans & pistachio nuts; it will grind them to a very fine powder in 5 seconds because of the high-speed spin of cutting blade. Very simple design, and for that reason I feel $35 is a bit too high for an Asian product.However, there are a few minor drawbacks: 1) for the simple mechanism of grinder, it is overpriced; 2) it takes practice in guessing how long to keep powered-ON for fineness of grinding, there's no setting to determine how fine it will grind beans/nuts; 3) oily nuts like pecans, almonds, and walnuts grind up into density sticky, gooey substance much like coarse peanut butter.But it is small, easy to charge, portable, and easy to use.
