The Epica Electric makes the benefits of a blade grinder seem more appealing than their limitations. The more we used it the more we appreciated its long cord, cord storage, and removable hand-washable grinding compartment. It only makes an "okay" cup, it's noisy, and it can't perform some of the tasks that burr grinders can. But it's a great blade grinder—stashable, travel friendly, and it grinds coffee for a fraction of the price that a burr grinder would require.
The Epica brand and the Mira brand seem to be identical grinders. We bought and used both through our testing and saw no difference. The Mira, however, does not seem to be widely available at this time so we chose to use Epica for the review.
