Do any teachers have the pencil sharpener from Classroom Friendly Supplies? I have read many positive reviews, but I think many are written because the teacher received a free sharpener for writing the review. I have terrible luck with pencil sharpeners for first graders! My electric one is dead and my wall one is hard for little ones to manage. The one from Classroom Friendly Supplies is budget friendly, too! Any positive reviews from this board? Thanks!
