Inexpensive bungees that are made from rubber are the problem, actually a ticking time bomb. It's not 'if' they will break, they will and what stored energy they have left will either smack what is around them making an audible noise, or they will break while you are driving and you may not know till it's to late. Either way bad news. My wife got me some bungees two Christmases ago and these are not made from rubber, but something else, they have holes through them so you can hook easy. I just can't think of the brand. When I get home this evening I'll post the brand, but these things are super strong and work awesome.
