My children have been home-schooled for most of their lifetime, but this year, my eldest daughter expressed a strong desire to attend public school. Although half the school year has already passed, the school required she have a "see-through" backpack for safety reasons, therefore, I went on a massive hunt for a quality book-sack that would last her another year.  Since no local stores had ANY in stock due to the time of year, I came across this one, and the ONLY one with positive reviews.  I ordered it, and it arrived within a few days.  Very satisfied with AMAZON!  On the 2nd day of use, my daughter walked in from school with a completely ripped backpack, barely clinging to her books.  It had torn from the seam underneath right at her back and all the way up one side.  Looks as though it just cannot handle stress from heavy books at all, maybe just a gym uniform and tennis shoes. WHAT A DISAPPOINTMENT, escpecially with such good reviews.  I returned it back to Amazon and am currently awaiting a refund. I would not recommend this bag to anyone, nor will I purchase another one.
