Query: Great Basic Pencil Sharpener

What can you expect from a battery operated pencil sharpener? With the Stanley Bostitch model, you can expect exactly what you'd expect from one that plugs in and costs $20 more. I'm very satisfied with this product. Nothing fancy, no bells and whistles, but a solid machine never-the-less. Very satisfied. Four stars - not because there is ANYTHING wrong with it, but because it lacks the fancy frills of more advanced models.
