In short, “As Is/Where Is” comes with a certain amount of risk and is in no way a “retail” transaction. There are no “guarantees” or “warranties” for any of the items that we sell.
We do strive to represent items fairly, to the best of our ability. We simply wouldn’t be around if we made a habit of burning through bidders. However, the ultimate onus of inspection and the final purchasing decision rests on the bidder.
Our best advice is do your research, physically inspect the unit, and leave enough room in your budget to accommodate any unforeseen problems.
