This is a dream come true!! As a teacher, I have seen all kinds of pencil sharpeners come and go.
The old crank ones were dull or usually broken. Then the kids brought their own hand sharpeners. They were always sharpening their pencils until they were an inch long, or we spent a lot of time sweeping up pencil shavings from the floor.
Next, came electric sharpeners. They never seemed to last very long. Then enter Imikas automatic electric pencil sharpener. WOW! I love this sharpener! It is sharp, collects the shavings in its own connected tray. When kids sharpen their pencils, it only goes as far as a nice sharp tip. They cannot keep going until no pencil is left. It stops when the pencil is sharpened. It is fairly quiet. The mechanics are metal with a sharp burr. The top and shaving tray is made of durable plastic. It is about 10 inches long by 3 inches wide. It does not take up a lot of space.
