It does not have Greek and it is a little annoying.
Otherwise, it is excellent as a device for someone who does not want many things.
Sound, microphone quality, battery life, and operating range are very good.

A very good phone that definitely does more than what I at least want from a landline phone, beautiful and clear LCD screen with many options on how it looks and a better menu than what Panasonic usually has, strong sound in every function, the only reason I give it one star and not more so as not to bury it is that the manual is only in German and French and even on the internet I hardly found it in English. Of course, from the moment you switch the menu to Greek, you won't need much help to set it up, but still unacceptable

We have it for about 3 months, and it does its job simply and correctly.
Obviously it's not a smartphone, so the menu is simple (and you will only use it for initial settings, and maybe the time, if you feel like it for phones), but it is what it should be.
Two small downsides: when you want to make a call, as soon as you press a button it takes a few ms to wake up from sleep, so if you are very fast you may end up typing "10xxx..." instead of "210xxx..", and the second one is that when a call comes, we first hear the phone from the bedroom, and then a few seconds later this one. Maybe it's because we have the ECO mode selected (but I don't spend time looking into it). But again, you get used to these things, it's nothing major, so the device is fine.

Readable bright screen, immediate response of the keys. The sound is loud. However, for the past few days, the headset has been experiencing repeated micro interruptions, making conversation difficult on one hand and unproductive on the other because the voice of the person on the other line does not have a continuous flow. Once, this problem was so intense that I had to end the call and speak on my mobile phone. That's all for now.

I cut a star because it didn't have a manual in Greek or English, but in Spanish...
Also, to a lesser extent, I am bothered by the menu structure and the ringing sounds, but not terribly.
A great advantage is the blacklist, as I was receiving a multitude of malicious calls from specific numbers, so I blocked them and found my peace!

Very good phone with good sound and build quality... typical Panasonic.
Its battery lasts considerably less compared to the previous Panasonic I had, but it doesn't constantly discharge.
I definitely recommend it for its price!
