Only lasted 3 weeks

I got his weighted blanket for my 11-year-old autistic son as he was in need of a new one. The blanket was cheap compared to other weighted blankets, so I figured I would get one and give it a try. Well, he liked it just fine and used it daily when relaxing. However, after only 3 weeks it had a hole in it and thousands of little glass beads were scattered all over the floor. And boy, are they hard to clean up!
