Why this gift works

The Panasonic KX-TGM450S Amplified Phone is a DECT 6.0 cordless home phone with a digital answering machine. It boosts voices by up to 50 dB with six tone settings, has a Slow Talk feature that slows the other caller's speech, a 112 dB ringer with bright red visual ringers, a large backlit display and keys, talking caller ID, call blocking for up to 250 numbers, and hearing-aid compatibility, per Panasonic.

For a 90-year-old who still relies on the home phone, hearing the family clearly is the whole point - and this is a phone built around that.

Who is this gift for?

Great for

  • Grandparents who miss calls
  • Hearing aid users
  • Keeping in touch with family

Think twice if

  • They have no landline
  • They need several handsets

The catch

It needs a landline or home-phone service, and caller ID only works if the service includes it; it comes with one handset, and extra rooms need the add-on handset; the base must plug in near a phone jack; and it is expensive for a home phone.

Skip if they have no landline service, or use a mobile phone comfortably.
