I bought this because of how cool it looks, but it has two design flaws they could fix if they made it a little smaller.1) It is heavy so if it doesn't fir snug in your socket, it can work its way out.2) It blocks the second plug on a two-prong socket.
Update. March 17 2021. Not a year later and it overheats enough that it destroyed phone charger and I'm worried it will start a firem how in the heck does it not have a 1 year warranty?! Holy crow feathers. Not ok at all This puts the FUN in FUNctional. I put mine on the end of a heavy duty extension cord. This is the best invention, EVER.
I love using this product and have three of them in my house, thinking of getting the extension cord version as well. My only real complaint is that it is a bit finicky to plug something in with only one hand. The device warbles a bit in the outlet. I would also agree that the USB ports are too close together, although I haven't tried to plug in more than one USB at a time.
