Sleek Design That Hides Cables Well
Color: White, Size: 3FT(13A), Color: White, Size: 3FT(13A)
This flat plug extension was super easy to set up and works exactly as expected. We mounted it on drywall using anchors (not included), but that wasn’t an issue since we already had some. The flat plug design is great for tight spaces, and it really helped clean up our bedside area by keeping cables neatly hidden and organized. Definitely a practical and space saving solution!

This ticks all the boxes. Nice long sturdy cord, rotating plug, sockets far enough to accommodate multiple devices, plus usb-a and usb-c. And mountable! Excellent product

Solves the problem of the ground location.
Color: White, Size: 5FT
In the master bath a lot of things need power. It really helps to be able to rotate the plug head to leave room for other devices.

Fabulous idea!
Color: White, Size: 3FT(13A)
I needed to puppy proof my sewing room. It has 4 stations for various machines and ironing. Lots of cords including TV, dyson vacuum, and computer. I bought two sizes, For my house the shorter one works from the standard wall outlet to above desks, ets. That included a small curve for positioning. There are 4 outlets, surge protected and c and a. My only con is the size. It is a very thick size. For something on the wall I wanted it flatter. The cord is a flat cord, and it came with connectors to put on the wall to contain the cords. If it were flatter it would be perfect. It is a bit bulky. It sure is very functional for all my needs. I also bought one of the stick ones which I would not do again. Heavy and even bigger to contend with. They both work well, It would depend on your own needs for the cord size. But certainly a good idea and the price is even better.

Does the job well
Color: White, Size: 1.5FT(13A)
I needed this as my wall outlet wasn't located near enough to my needs. Since it does exactly what the listing describes so, from my point of view, it gets 5 stars. Price was good. Well made.
