Query: A very disappointing pencil sharpener!

I took delivery of this "high end" sharpener with great expections. Unfortunately my hopes were thoroughly dashed the instant I first tried it out. All I can say in its favor is that it's powerful. Despite my every attempt at control, each pencil quickly ended up over-sharpened with an off-center loppy irregular cut to a uselessly sharp pinpoint. If the user doesn't keep a tight on the pencil the sharpener spins it out of your hand. Can't any manufacturer make a product that comes to doing the job one used to get from an old hand-cranked Boston screwed to the wall? How can other reviewers love this pig?~Gary
