Serene Innovations Cell Phone Ring Amplifier & Flasher – Cell Phone & Landline Phone Ring Detection with LED Flasher – Works with Cell Phone's Vibration Notifications – Extra Loud Telephone Ringer

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.

This is exactly what I needed and had been looking for quite sometime. When hearing aids are out at night, I cannot hear phone ring or text messages (elderly parent needs contact). I had found other products that worked for land lines but very few for cell phone. I thought I would need the bed shaker, but this is very loud, I will not be needing that option, but great to know it is available. Some reviews mentioned the constant blue light, it is very bright and may be a reason not to purchase if that is your issue, but I slide my phone over to cover the constant light and that is enough for me. Working out great so far.

Purchased to replace a Bluetooth bedshaker connected to my cell phone. This unit activates with vibration only, and the sensitivity goes from never sounding to going off with the slightest touch. Unit also has a light that is always on, incredibly annoying. It works but I would not buy it again

It's pretty simple in its execution. Set the ringer volume. Set your phone to vibrate. Put your phone on the "ledge". Make a call. It is a speaker with a pretty loud volume (its use case for us, as my Mom is hard of hearing) and the lights flash brightly. There's a sensitivity dial on the left side, but I didn't have to adjust it with the default vibration on my iPhone.

We use a cell phone for our home phone. We are both getting a bit hard of hearing, and I do wear hearing aids. Our phone sits on our desk so it's hard to hear it ringing if we are in another room This amplifier works great. The phone sits on the amplifier with the vibrate feature on. When our phone rings/vibrates the amplifier starts flashing lights & ringing loud. Another nice feature is it will flash slowly if we've missed a call, letting us know to check the phone. I give this 10 stars.
