Very good design, it fits modern rooms and goods. As a product of Panasonic which sells well at the home center, the type which the screw is visible on the surface is placed well, but with this one mouth, the good design is not put easily. I sometimes see 2 mouth things. Also, the internal screws and metal fittings are solid and very reliable. The only thing to notice is that when you attach the main body to a pillar or wooden work under the main body cover, if you screw the head screw that is too big, it will crack, so it is about that. The metal fittings in the outlet are quite high quality.
