A lot of the time I'm wearing headphones and can't hear the phone ring, this solves that. Happy with brightness of light and installation was easy, plug it in.

Worked as described, visible if mounted in view or dark setting. Easy install

This device simply takes the voltage from the phone line to light the bright LEDs. The like will brightly flicker with each ring. During the day, I suggest pointing the light toward the viewer(s). The reflection cannot overcome daylight/office lighting. At night, it can be pointed toward the ceiling so the flash is less harsh. I use it in a loud room where I may not hear the phone ring. In a quiet room, I have the ringer muted and let the flash signal a call. The unit could be improved by having non-permanent mounting (such as magnetic) and having the 'unit out' port on the same side as the wire in. Better yet, have a 'unit in' port with a short wire accessory.

Very pleased with this and has helped us a lot with our project. Thank you
