Hi-Fi Choice review the Mains Zapperator in their 'Choice Extras' section.
A short review in the 'Choice Extras' section of Hi-Fi Choice magazine (November 2012 issue) notes the potential of the unit to "absorb and dissipate RFI which is injected into the mains supply". It is particularly useful around wi-fi and Ethernet-over-mains networks whilst still allowing these to function without interference.
The Mains Zapperator is best plugged in to a socket close to your system to create a 'quiet' area around it. As the reviewer notes, this makes it easy to test the effectiveness of the device in your location "as it can be plugged in and unplugged at will".
And of the effect? "With the Zapperator, the music seems more lifelike and real. The edginess associated with strings becomes subtly more musical, mellow and effortless."
Magazine: Hi-Fi Choice Issue: November 2012 Verdict: Four stars
