Great little device
We bought this phone as we have limited mobile coverage at our place. It allows our children to keep in touch with us regularly and gives us a little peace of mind. It is compact and lightweight, and no fuss to set up. User interface is easy to navigate and has many different tones and sounds for you to choose from.Definitely worth the price.

Great home phone
A great phone with an answering machine that we leave on 24/7 to prevent receiving the scam calls, as genuine callers will leave a message, while scammers just hang up without leaving any messages, and after they hang up we can block their numbers too, but it would be handy to be able to save 100 blocked numbers instead of 50.

Compact, easy to use and setup
Great cordless phone and answering machine. Easy to setup, navigate the menus and use. Plugged straight into the back of my Telstra Smart Modem 3. The base unit with the answering machine is neat, easy to use and compact. I've always had Panasonic cordless phones as they are easy to use and trouble-free. Very happy with this phone.
