April 11 2020 This is the second time i have purchased this type of phone, probably not from the same vendor..but the phones were identical. And they both had the same identical flaw. They have a problem in how they are manufactured. The problem is that the one main button on the phone comes loose from the inner case causing it to get stuck. Thereby not letting you answer a call or not letting you hang up. When the phone works its great(see original review). When it happened to dad the first time i just ordered him a new one. But now its happened again with the second phone. As a temporary fix i opened the case and removed the silver button which wasn't attached anyway to reveal a smaller button underneath. The button i removed is really for looks only and it works fine now but there is an opening in the case now. I'm going to try to reach out to the manufacturer. this phone was a god send but if i can find one that is built better.... that might be the way to go. I hope they change the button on the front.(original) I bought this for my elderly father who could no longer use his cell phone because he just couldn't hear. I can now call him and have a normal conversations without screaming into my phone so he could hear me. It's very easy to use( one main button) and very loud. he has no problem hearing anyone that calls. The battery charge last very long. Sometimes when he goes out he puts it in his pocket and accidentally moves the switch on the side of the phone which changes the setting, and doesn't let him make calls. Now he's gotten used to it and checks the button first if he ever has any difficulty connecting to a call. Well worth the money!
