Excellent, does the job well!
Great for my electric pressure washer! The one built into my cord for my pressure washer was worn out, so I cut off my cord, attached a new end, then bought this. I like how it has 3 outlets and offers good GFCI protection. This is a great product!

This GFCI extension works perfectly!
This GFCI extension works perfectly! I use it to run Christmas lighting outside from my garage where a regular GFCI is not available. This protects the outdoor lighting from ground faults. It is clearly a heavy duty extension. Very pleased with this item thus far.

Very rugged and durable extension cord splitter. The thick gauge wire provides enough power to multiple tools. Well priced for the quality

Disappointed
Heavy duty multi outlet I purchased the DEWENWILS 3 FT Automatic GFCI Extension Cord Outdoor, 12/3 Gauge Extension Cord for Multiple Appliances, Heavy Duty Power Cable with LED Lighted 3 Prong Plug, Yellow, UL Listed In November, 2024 to help keep my water from freeing for my chickens. It was connected to a water heater coil. It worked all winter just fine. This summer I was using it for electrical tools for construction on a new chicken coop. When we plugged it up it didn’t work. We tried several other outlets and still would not work. Earlier this summer I had to replace a dog charger for fence and the charger quit working. I replaced it with a new charger and it would not work with the GFI extension plug I used in the winter with water warmer. Loved it at first but disappointed did not last over 6 months.

Returned the item. Item did not work for resistance based appliance. Used for patio heater and the gfi did not trip during overload. Would work for surge appplication. Changed review from 3 to 5 star as seller replied and provided more information about usage expectation from a gfi Good product just not for my application. Original Review: Noted as a GFI and I wanted to use to protect a fuse in the pane from tripping. When used the panel tripped anyways. Perhaps I don’t understand how a GFi works. But I purchased to prevent the panel from being impacted and this is not how it worked.

Very good product, works well in outdoor environments. Excellent for running multiple cords with out the worry of them grounding out and causing issues.

These things are hard to find in the real world so I had to order online. I was looking for something that would act as an inline extension cord GFCI where one didn't exist at the plug and it's performed well. The LED's are nice and bridge and indicate the status of the cord. It was easy to install and take apart in case of repair in the future. The extension cords seem like high quality and the GFCI also feels like high quality also. This product is great for provided protection against ground faults and it has the added bonus of being able to run 3 different items simultaneously.
