Review title: This thing zapped my phone lines!!
Product review: I was excited to receive the 2 units I bought but the day after I connected them, all my phonelines went dead. After three days of waiting for the phone company to come out to the house, they tested everything and said it was one of the caller id units that was causing a short in our lines. We couldn't even use the product and it caused a great deal of inconvenience. Very disappointed.
