I am loving it!

The new power strip that I bought from Ceptics, is right on top of my nightstand and I can reach it very easily. I do not have to search for a wall socket behind my bedside table or around the room anymore.

Great except no way to mount

Worked great to connect a TV & multiple USB casting devices. The only complaint keeping from a 5 star is that there is not a way to mount it to anything.


Must buy with the ever changing device power cords.

This strip works fantastically for the busy family and ever changing product chargers. All devices are thankfully contained in one location.
