Have had the box for a couple of years and it has served our purpose well. However, the flimsy hinge straps broke off within a year and as they broke the poorly designed thin plastic hinge structure immediately stretched and are now ready to split open . I was able to re-attach the straps immediately after they broke but the damage was already done and the hinge structure now continues to weaken with use. How could such a strong box have such a weak hinge structure?
