Bests & Worsts Reviews from Amazon

I have gone through three School-Pro Sharpeners in four years. When it works, this sharpener is wonderful. It accomodates several different pencil sizes, has a huge shavings receptacle and runs quietly. My first sharpener lasted through two school years. The second one lasted about a year and a half. The company replaced it for free after I complained. The replacement lasted only a few months. They all had the same problem. When a pencil was inserted the the blades would spin, but they didn't sharpen. I think there was a problem with the automatic pencil stop feature. If the company would address this design flaw, I would consider buying another School-Pro.
