If you are looking for a good, simple caller ID unit, here is one you should check out:
I have had one of these for a long time, and I needed another one, so I bought the same unit again. Here’s what I like about it:
* It doesn’t need a battery. Not only will the battery not run down in the unit, but also it won’t leak, because there is no battery. I don’t care if the stored numbers are preserved in a power outage, so I don’t need a battery in the unit.
* It is simple. Two buttons to scroll through the list of numbers, and one to delete a number.
* It is cheap. $5.87 plus shipping. (At the link I included above, shipping is free if you buy $50 worth of stuff.)
