Rated 5 out of 5 by GFCI Adapter The GFCI on my pressure washer went bad. This is a great replacement! September 2, 2014
Rated 5 out of 5 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 out of 5 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 out of 5 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
