I bought this X-ACTO ProX pencil sharpener 3 weeks years ago and loved it right away. It sharpens pencils evenly and was fast. Although, it is a tad noisier than others but the others don’t sharpen as well.
When you see the blue light you know the pencil is sharpened. I use this sharpener everyday, and it is a workhorse! It is sturdy and heavy like its built to last a lifetime. A definite Heavy duty sharpener! in my humble opinion.
