Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.

Good for my set up
Color: Black, Size: 15FT (Rotating Plug)
I have been using this to redo my office setup so that I have less cords going everywhere and this was the longest one that I could find with a bunch of grounded ports. I mounted it in a cable organizer under my desk and so far is going great. The cord length is perfect for what I needed because unfortunately where my desk is positioned in my office the nearest outlet is a ways away behind another piece of furniture. It was super easy to install because there's really no installation You just plug it in and you can rotate the cord in the socket so that it helps keep the direction easy for access to wherever you need to have it run to. It seems like it's durable I've had it probably 3 weeks now and the power has been turned off numerous times because of the enhanced safety features and so far none of my stuff has been damaged so I am thankful for that. I think it works well and I haven't had to use any of the USB ports or the c ports but I like that they are there so that as I add more stuff to my setup I have a place that I can easily plug them in.

Very nice power strip
Color: Black, Size: 5FT (Flat Plug)
It’s very nice that it has outlets facing different directions on the one side than the other. This allowed me to plug in a variety of different items including a smart plug.

Just what I was looking for
Color: White, Size: 10FT (Rotating Plug), Color: White, Size: 10FT (Rotating Plug)
Great solution for hiding all the cords coming from our tv above the fireplace in our apartment. Visible/untidy cords drive me insane and this worked perfectly to tidy everything up. It was much easier to run a single cord from the outlet to the tv along the fireplace and then hide everything behind the tv than it would have been to hide multiple cords with that plastic cord hiding stuff to the outlet/surge protector. This was super easy to install and makes everything so much nicer to look at while still having the surge protection for our devices. I also love that the cord rotates so it’s easily used no matter how your outlets or room is oriented.
