As many have said, the small bumps at the end of the outlet cause problems with most outlets. The good news is that they are pretty easy to sand/file/cut. I used one of those multi tools, but a dremel or even a good file will do. I would buy it again because the price is right and it took me 15 seconds to put it on. One star off for a stupid design choice. Annual update: Cable worked perfectly last winter. Used several times, once three days in a row. Soaked the whole house without any problems. Very important.
