Review on Efficiently Organize Your Lumber with Ultrawall Organizer Lumber Storage 3 Level by Beverly Smith

I'm installing them on regular drywall, ON the studs behind the drywall. The supplied screws are NOT long enough for this application. If they are NOT fully loaded, they will FALL off the wall. The screw strength was not sufficient. I hope the device will last if I get a longer screw. Just wanted to get this info right away! I am happy to improve my rating with an additional star! The longer screws I bought have held up and I love this product!
