The worse service bar none. At the time of installation (that was faulty) I purchased a service contract for a year. When the alarm didn't work properly I called for service and was told that sending a tech will cost me and that the contract only covers assistance on the phone. When I asked for that assistance I was told it only covers software support while hardware issues require a tech visit which I have to pay for, i.e. I paid for a contract that is worthless and I still have a faulty installation.
