I had ordered so many different kinds that I don't even remember the other brands, and models, but don't think I missed many. They'll all get used somewhere, but this particular one is a standout. You can use the straight sidewire clamps, that are very similar to the Levitron ones. The big winner is the TP things. It's hard to stick a bent paper clip in one, but the resistance is not irratating for a regular three prong plug like some of the others.
It's also nice that it's made out of good enough materials to work in damp locations..
