Two years ago, I thought I had finally found the best sharpener out there. It was very nice X-ACTO sharpener with auto shut-off, a little blue light that came on when the pencil was sharp, and an 8 year warranty. I thought I'd buy two so they got half the use and would last twice as long. Both failed before the end of the year. True to the warranty, X-ACTO has sent me replacements (3 now), but each of these has eventually died as well. One I'm currently using still sharpens well, but makes a sound like a dying animal.
