Takes up both outlets.

It's not readily apparent from the pictures provided, but this devices uses both outlets of a standard wall socket giving you a net increase of only one outlet, not 2 as might be assumed.  I purchased this for my kitchen in an area where I wanted to use the top outlet for an under-cabinet light and have 3 outlets available for toaster, blender, etc.  Didn't work like I wanted.  Oh - It's probably larger than you think it is also.

Outlets are so close together you can only plug in two devices. The USB ports make up for it, so overall good product.

Can use these anywhere.  Never worry about covering two outlets.

This switch is ideal for SOHO where POE is required and cost concerns are focussed on energy.  I have six IP Phones running on the POE ports, and one WiFi access point. Regular network devices consume 11 more ports. The total AC draw is reading 54w on my UPS!  This is quality equipment at a reasonable value.

I bought two of these for my home office. I removed the outlet faceplate and installed this with the screw through the middle. It isn't going anywhere.

The outlets on mine are very tight, sometimes I have to use another one because I can't plug something into one of them. That being said, they work reliably for everything that's plugged in. I do wish there was a little more space between outlets, but for standard lamp and computer plugs these are fairly reasonable.

I can finally can get rid of some of my power strips. I can't use all of the outlets because of the size of some of my plugs.

I've used this at 2 residences. This cube is so wide that it covers the other outlet on a 2 outlet standard wall plug. Maybe that's on purpose but it does limit your options. I've got 4 devices hooked into these and no problems so far.

This product was just what I needed to be able to take full advantage of my outlets!

I used this to plug this into all my power sucking appliances and equipment. I found some were using more power than I thought they were when plugged in and not in use. I have now started unplugging them when they are not in use. Lets face it we don't need a lot of stuff plugged in because they don't get used for days or weeks at a time. I have noticed a saving of few dollars in my electric bill over the last couple of months and it worth doing this because of that.  I would not recommend leaving it plugged in longer than you need to to get a good power usage reading. I don't believe it was intended to be used that way.

I purchased 2 of these 10-Outlet Surge Protectors.
I had outgrown my computer surge protector because I had problems with space for the numerous power adapter plugs.
This unit has allowed me to connect all the regular plugs and larger power adapter plugs into one unit.
The second one will be used in my garage once I figure out how to mount on a wall.
The one drawback to this unit is that it is not made for wall mounting, so I will have to "ad-lib" to mount the one in the garage (which should not be a major problem.

There are great for putting both a tablet and 2 phones onto one charger. It reduces the outlet use significantly.

Very convenient to have individual switched outlets.  The first device worked very well, so I bought another for use in another room.

This is a great light.  Love the motion sensor and the bright blue light.  BUT if you have limited outlets, beware.  this light takes up both outlets. As a result, I'll sadly return mine. Probably five stars if the design weren't such an outlet hog.

Worked well for all our devices. There were complaints of to noise from the fan, but I didn't find that to be true. It has three outlets able to charge multiple devices at the same time.

Outputs a lot of power, and you don't lose an outlet. Four ports-super convenient, and they put out the specified amperage.

I replaced my kitchen counter outlets with one of these and couldn't be happier about taking back the outlets from the chargers and also reducing the clutter on the counters.  The two outlets charge everything I throw at them that has a USB cable for charging and in my case, the size of the electronics still fit comfortably within the existing outlet box.

This requires a 3 pronged outlet and causes outages when I use it at the same time as my microwave.
