This device will wake you up. Wife is an MD and has to answer the phone when on call. Room lights and cell phone ringer won't wake her up. But this device wakes her up every time.

I do on call for work and can't miss a call. Was always paranoid I'd sleep thru a call. This will wake the dead. Works great

Works well with vibrator too. I have no fear of sleeping alone at night now!! (Deaf)

Husband is hard of hearing. Thus us a life saver. Love it.

Rings loud enough for my senior citizen mother to hear it when she can't hear the usual cell phone ringer. And she loves it so she doesn't miss a call now. Set up required fiddling with vibrate settings (since it's vibration activated) but I figured it out.

Being half deaf, I was missing calls while sleeping.Not any more

Great product!

works great, only dislike is it wil not work on first ring, it takes 3 rings to make it go off

Hearing impaired relative was unable to know when her telephone rang.

Brought for my son. Hard sleeper. Works great

I can hear my phone now.

What a lifesaver this has been! I wear hearing aids which I need to take out at night for sleep. Once I remove them, my world is very quiet and I sleep very soundly. Even with my phone amplified to the loudest ringtone, I don't hear my cell phone ring and have missed important calls at night. This creates angst and sleepless nights when I am on call for my work, as I wake to check my phone repeatedly during the night in fear of missing a call. Serene Innovations Multi Phone Ringer and Flasher has changed all of that. When I remove my hearing devices, I place my cell on the cradle, set the alert on high, and rest peacefully. The sound is alarmingly loud and the blue light flashes to alert you a call is coming in. It is tricky out of a dead sleep to push the reset button to turn the ringer off, but that is a small price to pay for a good night's sleep and minimal worry about missed calls. I do not utilize the attachment for emails and text messages alerts at night, as my primary concern is voice calls. I love that you can charge your phone while it is on the device. My hearing coworkers are interested in exploring this option as they also suffer from disturbed sleep when they are on call. This was a smart buy for me. Wish I had explored this option before.

Says what it does and does exactly what it says. What else can I say.

Was worried that my moms basic phone wouldn't work, but it works good. This is nice and loud and lights are bright,
