The Bostitch QuietSharp 6 Electric Pencil Sharpener is a classroom sharpener, but I use it at home and it is great. It has a one-hand easy turn selector dial with 6 sizes to choose from. The QuietSharp motor is very quiet and it sharpens very fast. The Tip Saver Technology stops sharpening at just the right time no matter what type of pencil is being sharpened. The shavings tray is very generously sized. The base is oversized and has suction cup feet for stability. There is a 6 foot power cord so placement should not be an issue either. The MagnaSafe safety switch stops the motor when the shavings tray is removed.
We have really been putting this pencil sharpener through the paces, with two school age children and two adults who always use pencil, it is used very frequently. It seems to be very sturdy and able to hold up to rigorous use. We have had to empty the shavings tray once already and it was very easy to remove and clean out. The safety switch allows me to have the kids do it without worrying about them hurting themselves. I would recommend this for any household, not only a classroom. Especially if your family uses a variety of different pencils.
