Review: Abysmal customer service - Purchased in July, therefore under warranty. In September, sound quality became so poor, neither phone calls nor answer machine recordings could be understood. The phone line for customer service is always busy and, when trying chat, was transferred to some outfit who , first of all, wanted money (maybe refundable, they said). I have gone back to my 20 year old AT&T phones. The sound quality is excellent and I shall never buy another Panasonic product.
Review: Fantastic - The phones have been working great since we purchased them.

### ⭐⭐⭐⭐⭐ Fantastic
*by S***D on December 16, 2025*

The phones have been working great since we purchased them.

### ⭐⭐⭐⭐ EASY SETUP AND USE. VOLUME NOT SUFFICIENT FOR MY 82 YEAR OLD MOTHER.
*by B***L on June 7, 2022*

GREAT QUALITY AND EASY TO SET UP. GOOD VALUE FOR THE PRICE. VOLUME CONTROL ON RECEIVER IS NOT LOUD ENOUGH FOR MY 82 YEAR OLD MOTHER. OTHER THAN THAT IT IS A GREAT PHONE / ANSWERING MACHINE.
