Bests & Worsts Reviews from Amazon

The display does not have sufficient contrast to be easily readable. The push buttons do not reliably make contact, programming is a nightmare if possible at all. Tech support was so busy telling me what to do that they DID NOT EFFECTIVELY LISTEN TO THEIR CUSTOMER. The Customer Service Rep actually hung up on A CUSTOMER! A MOST UNSATISFACTORY CUSTOMER SERVICE EXPERIENCE, SHODDY GOODS. The switch contacts on the inside of the face plate did not evidence proper cleaning so that button pushes were not reliable.
