Caller ID Model 132

This does what it says it will do - BUT it does not have a light when calls arrive. I assumed that all caller ID boxes had a light turn on when receiving a call. I guess I should stop making assumptions. This item does not work for me because when I sleep, I take off my glasses. I wanted a large unit that I could read without finding my glasses, then finding the phone. The product is so tightly sealed that I had to use a knife to open it, thus it is in no condition to return.
