These do a great job on the frig and freezer.

Solved my problem where my A/V electronics were interfering with X10.

Filters my ventless washer/dryer on a 15 amp 110 volt circuit. Corrected my noise issue.

I'm still experiencing difficulties and have not had consistent response with x10 signals. I was hoping several noise filters would eliminate my problem. Not convinced yet.

Difficult to tell if a filter is working properly, but at least it hasn't melted like the X10 10A filter.

I was hoping this device would reduce the electrical noise generated by my treadmill. It did not make any difference at all. I cannot listen to any radio in my house while my treadmill is in use. Even battery operated radios receive the electrical noise which makes it impossible to listen.

I wanted to be able to turn on/off a Department 56 Christmas village setup. I've read that the power supplies that run the little motorized/animated items can be noisy (actually some say they are signal absorbers.) Prior to purchasing this filter I was able to turn the village on with an appliance module but after that I couldn't turn it off due to the interference. I purchased this item, plugged it after the appliance module and before the power strip leading to the village. Now everything works perfectly. I chose this one over the smaller ones because I didn't want to worry about amperage. When using appliance modules they a rated for 15 amps so I wanted a filter that could match that rating.

A little large and hard to plug in a receptable and plug anything else in it.

ordered 4 and everyone works perfect.stopped noise problems.

Does exactly what it's supposed to. I'm using it on a landscape lighting "transformer" based on a switch-mode power supply which was creating a lot of noise on that particular electrical branch. Works like a charm -- very pleased.
