Less than three years old. Original owner. No issues. One outlet filters analog, another filters digital, and the third (middle) filters switch-mode power supplies. Probably the best you can find for a budget power conditioner. A few paint chips on the case.
Info on filtering from Dave:
"Here is how it works. All 3 receptacles have individual power filters. The center one has an additional stage built from the native wiring (Basically twisting the THHN wire inside into a very low value inductor that will not limit current but target VHF noise. The one that says “Digital” has a larger version on the filter package on the middle receptacle. These very low value coils work with the ERS to significantly reduce noise. The one that says “Amps” has a different subunit to help the amps transformers work more efficiently."
