Rated 4.6 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Excellent way to protect yourself! I have 2 outdoor outlets that are not GFCI protected. This is a great & easy way to protect myself while using these outlets when I am using an electric hedge trimmer or other corded device outside. Try to find a device like this in a retail store (including Home Depot) & the employees will tell you that such a thing doesn't exist! I've been searching for an item like this for years. The price & convenience are wonderful -You don't have to redo all your outlets - you just plug this baby into the outlet you are using and you are ready to go with no worries. I wonder why this item is not more readily available. November 12, 2011
Rated 4.0 out of 5.0 by Works with aquarium -- sort of I got one of these units to protect the electrical environment of an aquarium. Imagine my surprise when I turned on the fluorescent lamp above the aquarium and the GFCI tripped! I tried this a few times, with the same result each time. Apparently, something about turning on the light looks like a ground fault to the adapter. If I reset the adapter with the light already switched on, it didn't trip, but I can't be doing that every time I turn the aquarium light on. I ended up plugging the aquarium light directly into the wall, and using the GFCI adapter to protect the other things (filter, air pump, thermostat). So it's still useful -- it just can't be used to protect the aquarium light. Yes, I realize this could really be a complaint about the aquarium light instead of about the GFCI adapter....

Rated 5.0 out of 5.0 by Cost effective GFCI solution Needed to replace faulty GFCI plug did the job. Needed to add regular plug to device. Can now use GFCI in multiple applications October 4, 2011
Rated 5.0 out of 5.0 by GFCI Adapter The GFCI on my pressure washer went bad. This is a great replacement! September 2, 2014
Rated 4.0 out of 5.0 by Works as advertized This product works well. I bought it for my Aquarium so I wouldn't kill myself with all the electricity and water close together. The only issue I have is when the power is disconnected, either by turning everything off or a power outage the unit has to be manually reset. This could be an issue for me, if their is a power blip the system will stay off until until I can reset the unit. September 25, 2012
