Query: Dell AC Adapter

Horrible. They sent me an adapter that did not even work. It cost me money to ship it to me and then back to them. You would think they would test the adapter before sending it to me. They women at betterstufflowerprice asked me if the light on the adapter came on; it did not come on, so they used me to test their defective product. Very, very disappointed.
