Query: Terrible Backboard -- Read This!

I ordered one of these and, when it arrived and before I assembled it, I examined the backboard. It seemed thin and without much firmness, so I tested the backboard with a basketball. Good thing I did because the ball basically fell against a dead surface and the backboard vibrated like a trampoline, NOT at all like a backboard should!.So I promptly sent it back.Then, I visited 4 local sporting good stores (all national or local chains)to see what they had in stock and test the backboards of the display models. What I found was that ALL the Lifetime backboards are basically junk as are many of it's competitors. I am still looking for a portable system with the firm backboard like my old one (Spalding) but have not found it yet. Will keep searching.STRONG ADVICE -- Go to a sporting goods store and throw a basketball against the backboards of the models on display. You'll see what I mean.
