I have had them for several months now and I am satisfied with their performance. I got them to replace 2 other devices (different from each other). One had an issue with its battery and the other was simply very old. Before, I had to have telephone cables in both parts of the house. Now, with these that are a set, one has the base with the telephone input and the other base is just for charging, so you can put it wherever you want.
My parents, who are elderly, also use them, which is one reason I chose them. The buttons are large. When they are on the base, the screens are on (they light up and show the time and date), when they are off the base, after a while they turn off. You can adjust these settings; generally, they have other settings (for those who know), but I don’t use most of them.
I wanted 2 simple phones to replace the old ones and these serve me just fine. Their battery might not satisfy those who talk a lot on the phone, maybe it doesn’t last as long as someone would like, but when you have 2 devices, one will always be charging and logically you will never be left without a phone.
