Customer service/sales were very informative and patient in my questions over a period of a couple of days while researching, before ordering. Delivery was prompt, less than a week. Installation literally takes 1 minute., you open the box and plug it into an electrical outlet. No phone jack needed. We chose the watchband option. Put on the band, plug in the base - which is essentially an answering machine type device- then Push a button and wait until it all connects. One minute! We tested it first with just the connection tester. Later we pressed the button and spoke to an operator who was both kind and efficient. Absolutely nothing tricky, complicated or fancy. Exactly what we expected and paid for.
