Comes with a handy screw that adds a nice stability to the whole kit.

Awesome for my office, the screw is the best.

I like that this screws in so guests won't be tempted to take with them.

I love that you can make it more secure by putting the screw in the middle

It came with the right length screw and a washer if you want to remove the cover plate and use it in a more permanent situation, however it fits snugly in the outlet without the screw holding it in place

Mounting screw makes the product -extremely- sturdy

Only the screw needs to be replaced as the wall plate will not interfere with its installation.

Recommend using screw to keep it secure

It comes with a nice long screw to go through the middle

Great, center screw to keep in in the outlet, plus a USB charger, bought 3 will buy more!!!

It took under 2 minutes to install and that is only because I had to find the correct screw driver for the single screw needed

A screw and washer is included to secure the outlet to the existing duplex wall outlet by removing the existing outlet cover plate screw

Mounting screw makes the product -extremely- sturdy

I especially liked it included a one inch long screw to replace the shorter one when the wall plug in expander replaced the wall cover on the wall recepticle.

The bottom line is that, unless you fasten the unit to the wall (using the included screws) it's entirely too easy to

Love this thing, the included mounting screw is perfect

inserting or unplugging with one hand moves the whole unit to the point where I'm afraid the lone screw might start yanking on the internal outlet.

works great and having the screw in option in the middle is important!
