Query: Showed up broken

Mine showed up with a broken mechanical piece that probably holds the whole spring system together. I wrote to them but expect it is more expesive then the unit is worth to ship it back for repair or replacement. It looks ok if it would work, but is completely useless to me. They have written me with instructions to repair it myself and I will try and let you know if it works when I have the time.
