A ball against the "post" (post is of course said a bit too much, it's more of a relatively thin metal tube segments) shot and then whole construct is already badly shaken. Moreover, it is surely only a matter of time until it disfiguration / bends. And I'm not talking about one of a normal football leather but a lighter plastic ball for young children.
But taking into account various weather conditions, rebounding to the metal rods and balls of rather average power quality, I assume that this goal might hold for a currently-threes so maybe 24 months. Then it would be fine for me.
Who really is a little more stable gate looking for older children should possibly look for something different. Considering the material quality and the price, I think three star is appropriate.
