It is all based on where you live. I have found that I can get it worked on by anyone with an engineering degree. You really don’t want to try to get this worked on by Ziess. They don’t really want to fix them, they want to sell you the new model. Any work they did do would be charged at $150 per hour, and they don’t necessarily support all the spare parts you may need.
On the positive side of the equation, spare parts are available on Ebay, and anything you could break can be replaced modularly even if you don’t know how to fix it, as the entire piece breaks down into smaller sections. If one can handle an allen wrench and a pair of pliars, one can swap out sections on these units.
How do I know all this?
Ziess said that The Transportation Security Authority caused $7,000 worth of damage to my rig trying to find a bomb, or drugs, or whatever excuse for their existence they are fobbing off these days.
Does anyone want to hazard a guess on how much they offered to pay towards the damage their unmerited mishandling caused?
