Serene Innovations Cell Phone Amplifier & Flash Ringer – Cell Phone Call Alert, Home Phone, & SMS Detection with LED Flasher – Works with Apple & Android Phones – Adaptive Telephone Ring Amplifier .

I have a 'dumb flip phone' - that is hard to adjust volume for text msgs - have missed several important texts at night - calling for prayer needs or emergency - and found this FABULOUS unit that operates by VIBRATION! - can set phone on it on bedstand at night - has both volume and vibration sensitivity adjustments - and WORKS PERFECTLY!! not one msg have I missed - sends both sound & special lighting alerts - and has bed vibration attachment to purchase if needed - is truly an answer to my prayers - as I can sleep deeply, peacefully - knowing will miss NO more calls or msgs again . . Am truly SO GRATEFUL to have found this important device!!

Couldn't hear my cell phone ring and this magnifies it for me and will charge my phone

The bed shaker no longer vibrates and i have only had it for 4 months.

The Cell Phone Ringer/Flasher works for the most part, I've only had the device a few days and so far it wakes me when my phone rings. I bought this because I'm hearing impaired, and when I remove my Hearing Aids and go to sleep I can't hear my Phone ring. It could be much louder, it's actually not that much louder than my Cell Phone. I would prefer the blue LED flasher be clear white, the blue flashing light may as well not be flashing at all. Still, it wakes me when my Phone rings and that's the reason for the purchase. So I would recommend this to friends and family.

I am deaf not sound but flash cell phone
