MAKES ALL THE DIFFERENCE IN THE WORLD. CLEAR CONNECTION NOW. nO MORE STATIC

Plugged it in and the awful static was gone! Why didn't I think of getting one of these sooner!

I guess it works ok.

This item resolved the phone static my high-speed internet was causing. It arrived safely and promptly. Thanks!

works fine

Great - the product works as expected.

Out phone service includes DSL Internet. The phone line filter helps remove most of the noise in the handset caused by the DSL. There is still some residual noise when using the wireless headset but it was worse before installing the filter. I recommend using the filter if there is any phone noise regardless of the cause.

it seems to be working, I also had to buy another one for the printer, I was getting fax machine noise on my answering machine.

filter is ineffective.

It was supposed to kill the high pitched squeal that our new ATT cordless phones emit when screening a call It does nothing.

did NOT make the new ATT portable phones work. Quite disappointed in filter and phone.

It did not work. Still had same amount of noise.
