Works perfectly. No more multiple steps clutter.
Under our entertainment unit we have 9 separate plugs and we want the electronics on a surge protector. I had used the 6-socket surge protectors I had on hand and ended up having to use 3 strips to plug in my 9 components because some of the plugs were bulky and covered more than one plug. It was a mess. This solves the problem.
The way the 2 sockets on this strip are offset from the rest, I was able to plug in my bulky plugs without covering any extra plugs so I ended up with 9 more sockets than I needed, but I would rather have too many sockets than not enough.
Before plugging in my components I checked each and every socket on this power strip and all 18 sockets work perfectly. Also, I had no problems getting my plugs to fit, unlike some of the reviewers who complained about the sockets being too tight. The power strip is light weight, but it seems well-made and sturdy. I like the 8-foot cord length which made it easy for me to position the power strip where I wanted it. A 6-foot cord would have been a little short.

It's a 7'cord Not a True 8' cord
It's a 7 ft cord the 8 ft they count is the actual plug unit which if you add that totals 8 ft at the very end of the plug unit. Again to clarify the cord only is 7 ft only. The USB ports are not that fast charging I still had to put my fast charger into one of the plug slots not the USB slot and charge my phone off of a plug. The USB would be satisfactory for things that just sit around on the desk. The overall size of the plug unit and the number of plug ports and USB ports is good for my needs for the price that they asked. It came shipped well packaged and on time.
I think that overall it's worth the price if you keep the above things in mind that the cord itself is only 7 ft and the USB ports do not fast charge to the same degree that a fast charging USB plug unit would make your device rapid charge.
Personally I feel that saying that the cord is 8 ft when it's only 7 ft and trying to include the plug unit into the length of the cord which by name they are totally different things is misleading and a false advertisement on the part of the seller or any seller that does their ad to the customer's disadvantage or misinformation. I was really counting on the cord being a true 8-ft not including the plug unit. That's how I measured according to my needs and it wasn't a true 8 ft cord.

Plug and play
Lots of plugs, USB plugs, and lots of room for plugs. What more could you ask for? This works great. Like everyone else I feel like everything is electronic anymore. Our house was built in the 70’s so our plug to room ratio isn’t so high. These are great to help with all of the items that need power. Great price, design and works great!

Finding a good plug strip without blasted usb ports
It was surprisingly difficult to find a good plug strip that did NOT have USB ports. The last thing I want on a plug strip that I'm going to stuff behind a bunch of monitors are usb port electronics that might die after a few years. I get my usb power ports from an Anker that I can situate on the desk. So, A+ ... this plugstrip has no USB ports! Yahhhh! That and other things I liked about it:
* Yippee! A plug strip that doesn't waste space adding USB power ports that I will never use.
* Very good plug layout. With all the adapters and misc plug types I needed to plug in, I thought that I might waste too many sockets with covering cords or adapter plastic. But it turned out that I was able to arrange all the plugs and adapters with very little 'wastage'.
* Having two orientations in the design made a much bigger difference than I thought it would. Kudos!
* And spacing out a few of the plugs also made a huge positive difference, reducing covering wastage from those odd-ball adapters that just like to take up a lot of space.
The only thing I can dock this strip for is that I gave it four stars for sturdiness, simply because sometimes a plug would 'catch' on something inside the strip if I didn't push it in exactly straight. Not a big deal really, so I gotta give this guy 5 stars overall.
