This phone stinks:
Half of the time I cannot hear the other party unless I hang up this phone and talk on one of my old phones.

phones:
Very easy to use and operate, wish the volume was louder on speaker phone and ear piece I like them quite well

Typical Panasonic:
This phone Panasonic KX-TG5623B Black 5.8 GHz FHSS GigaRange Digital Cordless Telephone with Three Handsets initially worked well. However, when the battery needed replacing, Panasonic no longer supported the product and the handset became useless. You cannot add additional handsets to this phone. I would not purchse this phone again.

Too many failures - Can't recommend:
We purchased these phones on the obvious feature of having 3 related but separate phones and chargers. The sound quality was not the best, but acceptable, especially if you use the feature to brighten the voice quality. Within 3 months, the base station unit died. We sent them in for warranty work, and were surprised to get back refurbished units. We did not like it but figured, what the heck, given that the turn-around time for replacement was less than two weeks. We are now about 9 months from that replacement, and the base unit has begun to malfunction. People call and can't hear us. We can't dial out, etc. I am scrapping these, and returning to good old corded units that I can count on the performance and quality.

Serving us well:
Panasonic KX-TG5631S 5.8 GHz FHSS GigaRange Digital Cordless Answering System I've had this system a good while now. I looked at lots of reviews before making my decision and have been pleased. I have a Vonage account... Internet telephony... and it has voicemail and call waiting built in. I plug the Vonage router into the high-speed modem, and the telephone base into the Vonage router. The sound on the phones is great, the range has been very good. We have two home offices... so we have one phone in my husband's office, another in mine, and another in the living area. Have not had a problem... ever.
