I would always suggest that rather than taking the seller's word for it, they should see the product running, in operation, in the person's home. They should be the person that removes it. I think it's unrealistic and unfair to expect that the seller should take it apart, turn it into a bunch of loose pieces, ship it somewhere, and then hope that you can put it all back together again. I think that is really unrealistic. I think it is reasonable, if the unit is operating and you can see that it is operating, you can see the condition. Then you buy it and then you take it apart. You participate in the dismantling, and you participate in the reassembling.
