We got the warranty when we purchased our house. I've had to use it twice now on relatively small things. In both cases the repair was completed within a day, by technicians who were clean, professional and prompt.
But here's the AMAZING part: Each time I have submitted my claim online via their website, my cell phone rand within minutes. It was the service guy calling to schedule an appointment. The last time, it was more like seconds; I hadn't even finished printing out my confirmations when my phone started ringing. Now THAT'S SERVICE. Companies across the globe could learn from that level of service.
