Very bad device. During a call, it makes noise especially when talking on speakerphone. I changed it and would not choose it again.

If you want something simple and affordable, it's the best. If you want color screens and technology, dig deeper into your pocket

As for the sound quality, it's great both when it rings and when you talk, but I don't know if some interference that occurs during a specific call is due to the device or the other person's device. Definitely a downside is the lack of user instructions in Greek

Returned back to Panasonic after owning a Philips wireless phone, you just cant go wrong, one star removed due to echo when using ( the very loud ) speakerphone option but this might be due to the Vodafone land line I have and not the dec.

The important problem is that it does not have call blocking capability. The usability of the menu is low. With the same amount of money, you can get better products

I have bought many cordless phones from different companies. The Panasonic KX-TG2511 cordless phone is flawless in terms of functionality/use, the best one I have bought. I have had it for 6 months in blue color. The sound, the buttons, the speakerphone, and the range all work perfectly. The screen has normal-sized letters & numbers (but probably not suitable for elderly/senior people).
In ECO mode, with daily use of 2-3 hours, it needs to be charged every 10 days.
If I had to mention something negative, the user manual is only in Italian (there is a Greek version available online) and the menu is not the easiest.

Continuing with the commentary,
It has now been a year in my possession and it continues to work flawlessly!

I have the impression that it amplifies a little and I hear my voice when I speak. Otherwise, it seems like a decent phone and the battery lasts a long time.

I had the equivalent previous model and chose this one now for the open hearing. The open hearing does not work - it makes noise, static, etc. The rest of the conventional things work fine. It's just that ultimately the previous one would do the same job and would be more economical.

The open listening and ringing suddenly stopped after a few months of operation.

Good telephone device (I think the best wireless ones are Panasonic), BUT the manual is in Italian??? (Not even in English...). I think there is something about this in the legislation....

Exactly what you need for basic use. It is definitely a purchase that no member of the family regrets.

The only negative thing is that I struggled to change the menu from Italian to Greek.
Other than that, it's perfect.

All good.

Unfortunately, the phone did not have the user instructions in Greek but in Italian! (With a little searching, you can find it online). You get used to the menu, especially if you had a Panasonic phone in the past. It has a small screen, but you can put on reading glasses and see! The truth is, for its price... it's a great phone!

The only negative thing is that there are no instructions in Greek and that the phone is set in Italian. With a little searching on Google, you can easily find out how to change the language though, so don't get stuck on that. Other than that, it is excellent for its cost.

Very small letters on the screen. It does not serve those with presbyopia or older age. Also, the ringtone is not loud enough.
With the same amount of money, you can get another model from Panasonic that covers the above.

It has excellent conversation and open listening acoustics. It does not have any conveniences such as illuminated buttons and user-friendly menus.

It broke in 6 months, it doesn't have an open speaker and it doesn't have sound when someone calls. Get something else with the same money, I believe it will be better for you
