I didn't realize how poorly made they were until I installed all ten and then the first time I unplugged one it broke in the wall box. I'm not going to take them all out of the walls to return them as I don't have time for that at the moment and I think I've already thrown away the packaging so I'm just hoping I survive to see that I have the time and got the money to replace them all. I would take them and send them all back if I had the packaging.
