Never missed a call since,
Verified Purchase(What is this?)
This review is from: Connected Essentials CEA20 Flashing Telephone Ringer Amplifier (Electronics)
I bought this ringer as a present for my Gran as she struggled to hear the phone when she had the TV on. I have to say the combination of a flashing light and loud ringing volume are a great idea and she is thrilled with the purchase - she's never missed a call since!
