It came relatively quickly. Set-up went easily. But when there was an incoming call, neither could we get the plugged-in house phone to answer, nor our cell phone. We had to note the number that was calling and then call them back. The house phone would make a call out, but only after entering a code. We were unable to get the device to work with other phones on the in-house wiring system. After a week and several re-hook-ups, we threw in the towel and now just use the cell phone by itself.
