Good set if you need more handsets


I ordered two of these handsets to replace two original handsets that went bad. Installation was very easy. I'm glad that I was able to replace individual handsets without having to purchase a whole new system. Will probably purchase one more set to...

Excellent additional line!


The phone helped put up additional line when one of handset was broken. Best part is that it was plug and play - attached once to base set and it recognized and downloaded all contacts in < 1 minute and ready to go !!!

Gets the job done


Wanted to expand my set to a fifth phone so I would have a telephone in the basement. This is just what I needed and setup to link with the base was very simple.

Still trying to get it to work


We purchased this as a 4th extension to the system we purchased. The instructions said all we had to do was plug it in and it would set itself up. The extension still says it has to be registered. We need to try to understand the manual to set it up.
