This is soooooo very cool to use. It allows me to use it in so many other sockets that I could never really use due to their location. It makes it easy to swivel the plug to the position needed. It is sturdy, a good price, and the cord length is just right. I will carry one in each of my backpacks & computer bags, as well as it will replace most of my extensions. The weight was right so that I could put it in my backpacks and having all of the outlets makes it very useful.
