Summary: My mother in law is hard of hearing, and is suffering from alzteimers. Many times, we could not reach her, merely because she didn't realize we were calling. No problem now. I also like the one button on and off, she had no problem knowing how to answer it.
Summary: I have a modest hearing loss. Phones were a problem and answering machine messages were a bigger problem. This phone has several features that work to compensate my hearing loss. So, I'm very happy to own one. It's pricey. Buy another phone if you don't have hearing issues. If you do have hearing problems then the C4320 is a real bargain.
Summary: I like the phone, don't like the retailer. Compute4Less said it was in stock, I paid for 1-3 day express delivery, they confirmed in email, then I follow-up on day 5 - where is it? they say 10 more days and don't answer the phone or emails. I'll never believe Compute4Less again.
