Update to my previous post.
Spent most of the morning trying to get a hold of Kidde when I finally got through I was given another number to call and was on hold for about 25 minutes before someone finally answered. Was told that my unit replacement was on back order and that they did not have any idea as to when I would receive my replacement. I then explained to the lady that I would be leaving the US in about a month and had no idea as to what would happen to any shipments that would arrive after my departure. I then asked her to change the address so that it would go to my Canadian address but she said that she was not able to do this, that when I got back to Canada I would have to start over again with the reps there. So I guess that I will just wait and see . Not impressed with them at this time.
