Most electricians used to use Raco but they aren't as good now. The box is now mostly aluminum which isn't a problem, but the 3 plugs that come with it are plastic and that gives these 4 stars. If you install it where it will be exposed to the sun the plugs are not as durable as aluminum and there was a time when you had enough plugs for all but one of the holes. So if you only use one hole, like the socket at the end of an extension cord, you won't have enough plugs for this box. I bought it for about five dollars and see that it now costs more than eight and not worth the price. If you see it for the price I paid I would highly recommend it and suspect most users would give it 5 stars.
