2PCS 95dB Extra-Loud Telephone Ringer Phone Ring Amplifier Ringing Help Strobe Light Bell Sound Landline Ringer Sound Ringtones

Very loud easy setup

Loud and Clear.Ringer really does the job. Easy to hook up and does exactly as expected.

We installed this for a nonagenarian who takes out his hearing aids at home (not a good practice but tell me people don't all do it from time to time, for comfort and quiet.) So if you have someone who has trouble hearing the phone ring, this is terrific. It's loud and it flashes. We put one in the sitting room and one in the bedroom. You could add one in the garage or workshop if that's where they hang out or even on the sun porch. We also added a large button landline phone unit for ease of dialing.

Sound

This does not work on all phones. When I pick up the receiver the Telephone Amplifier keeps ringing and it doesn't recognize that the receiver is off the hook. it just keeps ringing and ringing.

I purchased this solely to provide visual indication of an incoming landline call while I'm wearing headphones. I removed the back cover with the single Phillips screw, and snipped one of the white wires going to the speaker. This is a very low tech device, using ancient through-hole components. If you need a brighter indicator, consider replacing the red T-1 LED with something brighter.

Good thing

I have a simple landline phone I use to connect with a gate, and over time the volume kept getting lower and lower on the phone, so I couldn't hear when someone was at the gate. I plugged this in and BOOM!!! The whole house is now filled with a ring when it goes off. It's awesome.BTW - the comments about it being cheap are totally irrelevant. Yeah it is, but so what. It works great, and having it made out of stainless steel or gold wouldn't make it work any better. And to get 2 for this price - perfect!Also - remember to get a simple phone line to use too. I picked up this one for instance: https://a.co/d/5HChGEW
