Attractive and functional travel power strip
Color: White, Size: 5FT (3 USB-C)
As pictured. Nice quality. However I wanted US electrical certification to use it in my older apartment.

Manufacturing Flaw
Color: White, Size: 5FT (2 USB-C), Color: White, Size: 5FT (2 USB-C)
I removed 1 star because there is a manufacturing issue and bad packaging. This product is actually great. It's exactly what I needed. There's plenty of outlets and a good amount of USB and USB-C ports to charge additional devices without using any charging block. There's a small switch to turn off/on the entire outlet. What I love the most about this product is the rotating 360° plug. It saved me so much time and effort to organize my outlets/plugs. Its a very unique design and definitely something different on the market.
Now, here's the flaw. The flat cord are twisted and does NOT sit flushed against the walls. Once you plug it in, and line up the cords, the outlets face the walls instead of outwards towards you. It doesn't make sense. You can't install the outlet to the wall because it will never lay flat like they claim. You cant have it sit on the floor or table without it flipping over on its side because of the twisted cord. And also, the packaging wasnt so great either. I would assume a great product would come with great packaging. It should look and feel more of high quality like the product it self. Overall, its a minor flaws and doesn't change its functionality. The purpose was the 360° plug, the extended 5ft cord, and the extra USB-C outlets, so I will keep it. Besides its actually affordable and pretty much durable compared to others.

Good extension cord
Color: White, Size: 10FT (2 USB-C)
I have an upside down plug halfway up my wall that was really difficult to use and this is really been a game changer. It's flat against my wall so I'm not going to hit the cord and it it's long enough to put it in a more usable spot in the spare bedroom. The USB ports come in handy so I can keep the outlets free for my TV, lamps etc.
