I'm sorry, but I just don't see it that way. If there is fault with the product not made clear on the listing, negative feedback is far from uncalled for -- irrespective of whether the buyer decides it's worth keeping anyway.

Bear in mind that shipping replacement arms from the US (including postage) is costing more than the entire original purchase - again including postage.

As I have said to monster_truck in a private message, I would be happy with a partial refund to reflect the fact that the good really were not as described. If monster_truck is expressly unwilling to provide this, then we advance to the next step in the dispute resolution process.
