I have about 4 of these 8300 over many years. I like it for a basic phone.  Unfortunately the replacement I bought on Amazon *(first time) had problems.  The zero key doesn't always work and this week the voice microphone went out so I can only use speaker.  Furthermore Verizon doesn't not send OS updates to the phone so the new phone is several version behind my older phone.  Very disappointing.  Oh and I don't see a warranty on the phone,.
