Title: Great for Moderate Classroom Use
Review: I am now ordering my 3rd of this model of sharpener because it lasts better and has better features than some of the more expensive sharpeners. I went through several 1 year lifespan sharpeners before hitting upon this one. My last KP-310 endured almost 5 years in a middle school classroom, and the one before it lasted over 3 years. It has required minor repairs (mainly a good cleaning) from time to time, but the blades stayed sharp for a long time. For the price, I don't think you can do any better!
