Query: Terrible Design - Stay Away

As other reviewers have noted, this sharpener has all sorts of problems - noisy, slow, jams a lot. The worst part, though, is that it only sharpens one side of the pencil, which results in a pencil that is largely unusable when sharpened. I actually bought an expensive pencil thinking I would avoid this problem, but turns out otherwise. Stay away from this device - it's terrible, especially given the premium price.
