I bought it mainly because of the eco plus feature that very few wireless devices support. Personally, I am marginally satisfied, but what can you do if there is an elderly person at home who can hear just fine with the landline but struggles to hear with this? It is simply unacceptable for the manufacturer to have limited the sound volume so much. Just because of this issue with the low sound volume, it gets two stars at most. Without the eco plus, I would have given it just one star.

Sound quality is average, nice menu and easy to use, the battery is mediocre. I have had it for 2 and a half years and since yesterday the microphone doesn't work, meaning I speak and they can't hear me

It is good overall, not in terms of batteries as they had low capacity and I had to replace them. The bad thing is that gradually the LCD screen broke, with some digits resulting in it being unusable...

The 2nd one I'm buying. Top. Powerful sound, endless battery if you use a rechargeable one, the only downside is the somewhat unreadable letters on the screen. The first one broke after falling from a high point.

I see many negative reviews and I don't know why I bought it for my work with many hours of use and now, after one year, its battery lasts for days with its own batteries

Okay, for its price, I didn't expect to get something better, but it's not the best either. Its battery is not very durable, the range is small, and the sound quality is like the ones phones had in 2000...

Update: After two and a half years, the screen of the product broke and the numbers with the indicators appear dim or half-visible. I had bought it cheaply back then for 17 euros, but now I see that its price has increased, so I do not recommend it.

I bought it for about 20 euros just to have it at home. The only issue I have noticed is that it doesn't have a high enough volume when speaking, even in open listening, so I wouldn't recommend it to older people or people with hearing impairments. Also, the letters are a bit strange until you get used to them.
It supports call recognition and stores the numbers that have called you, and it can store up to 50 numbers in the directory. Definitely, for its price, it is one of the best options available.

From the first day I bought it, it has been giving me trouble. Conversation becomes impossible. And the volume of the headphone is very low

For its price, it is very good and in relation to what it plays. It has several capabilities, you just can't find them all unless you have the manual in hand.

It's fine for the simple use I make of it. I don't have it off the base for a long time and I don't take it far away. It's good in use (for its price?), the only negative thing I found is that the interlocutor sounds a bit quiet.

After a few months, the user experience is not particularly positive. The sound in conversations is very low, even though it is set at the highest level. The speaker is not heard loudly and it is difficult to communicate.

It has everything one can ask for in a home phone. Alarm clock, eco function, call block, keypad lock, clock with date, phone directory. It's great for 20€.

Edit: After about 1 year of use and a lot of mishandling, I have to say it's excellent. When the kids are asleep, with one press it becomes silent without having to search in the menu. The slightly difficult-to-read screen is a matter of getting used to. I highly recommend it. Urban myths like PANASONIC = UNRELIABLE have now collapsed.
