Very easy to hook up. But not as bright as I hoped. But it has been serving it's purpose.

Would have been nice if it came with an adaptor for older wall phone jacks. Couldnt use it

Matches description

Good product for those hard of hearing to know when the phone is ringing.

Great for hard of hearing gives ample lighting when phone rings

Unless you're looking at it, you probably won't see it during the day...

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.
