Review: Works great - This is an additional unit in our system. The most you can get in a system is five units and we wanted six. This unit will not operate by itself...it is an additional part of the system. Love the system. It does a lot more than indicted on-line with gobs of options and after you learn that you must precede the option number with a # it is very easy to program. You can store up to 3000 names!
Review: WORTH THE PURCHASE - A quick delivery and a helpful enclosure make this an easy transition. The additional contact number if needed for additional help is a nice touch. My suggestion is to include following in the informational enclosure: charge fully - go to settings - register phone.

### ⭐⭐⭐⭐ Nice phone system
*by L***R on November 23, 2020*

Easy to program. Sound quality good. Occasionally calls come through as faxes when they are not. Did not have this problem with set they replaced. I have 6 handsets on this base. Lightweight. Reasonably priced. Don’t have to use a phone battery. Can’t do three way calling which I miss. Long battery life.
