## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Working great for controlling an electric floorpad heater while generating little RFI
  

*by A***H on Reviewed in the United States on March 14, 2021*

I have an electric (heated) floor mat under my desk for my feet. It runs too hot when my feet are in socks, so I put it on a dimmer. That worked but caused static on my speakers and headphones, and worse, on my microphone.It looked like this device had a different electrical design, so I tried it in place of the dimmer. There is still a little static with the setting between 7 and 10, but lower settings and full-on produce no noticeable RFI.I screwed it down to a board for safety and convenience, since the terminals are (somewhat) exposed.I've had it running full time for several weeks now. This device never gets hot (or even warm), and my feet (and ears) are very pleased.

    Does not work
  

*by J***S on Reviewed in the United States on January 8, 2020*

Absolutely no change in voltage or amperage. Does nothing.

    Variable speed switch
  

*by J***E on Reviewed in the United States on August 9, 2021*

This unit appears to be very well constructed and will be used in my home built rock tumbler.  It is constructed for easy installation and the connectors are readily accessible.
