Caller ID with Call Waiting CI 43 - Digital Caller ID Display for Landline Phones - Perfect for Home, Office & Business Use

Bought one of these years ago and it eventually wore out, I guess from old age (?).The display got too weak to read in spite of contrast adjustments. Considering the unit's age and the amount of use, it was a real workhorse and bargain. Have been looking for another one since. This product works well for me. To work properly, like a sargent in the Army used to say, "When all else fails, read the directions". The selling feature is the Call Waiting ID which is hard to find. I had another caller display from Radio Shack that was a pain to use because you HAD to use batteries. With the Bell South item, batteries are optional (but recommended to save information in case of a power outage). It has a lot of features not found on other similar units, and the price is very reasonable. I recommend this item for the price, features, and ease of buying on Amazon (hard to find these - I wasted gas money driving around looking).
