In schools without lockers, students are sometimes provided with two complete sets of textbooks, one set being kept at school for use in class, and the other being kept at home for referring to for homework, thus limiting the amount of heavy carrying that would otherwise be required without having lockers to store them in between classes.[1] However, research has shown an increase in the incidence of back injuries in some students, which has been directly attributed to the lack of lockers for storing books in, thus forcing students to spend more time carrying heavy loads of books in backpacks.
I must stay, I was a little reluctant on buying this product because of the lack of reviews, but I am not disappointed at all. This product is EXCELLENT. I was a little overwhelmed with the installation process at first, but after emailing back and forth with the seller they were able to send me step by step video instructions. It was super easy to install and looks great. The individual keys are very well made. Highly recommend it
