Quick little review after I installed it.
Overall, it’s one of those things that you wish you had thought of. It is definitely a good thing.
Its a regular outlet with a side module for the USB plugs. It gets power from the outlet and regulates it to the 5 volts USB devices needs.
The cover plate is also a regular one, with the holes for the USB plugs seem to be laser cut in.
About the only downside is that in my particular outlet, it was a tight fight.
