Is the following review positive or negative?

We have had a contract with National Home Warranty for approximately 9 years and it's one of the best investments we've made. They are courteous and professional at the office as well as the technicians that have come to our home. I particulary like the ease of using the plan. They call you 30 minutes in advance to inform you the tech is in route which allows me to leave work and meet them WITHOUT having to wait around the house all day waiting for their arrival. The annual fee is reasonable and they mail you in advance and allow you to make the payment in (3) installments without charging additional fees. The combined annual fee that I have paid over the last 9 years is still considerably less than all of the items they have repaired or replaced. I have recommended them to several friends and neighbors and will continue to do so. Susan S.
