Review on Leviton SmartlockPro Weather Resistant Tamper Resistant Receptacle by Scott Ward

The tricky little test and reset buttons make it difficult to use, as at least one other review commented. But to make matters worse, out of the two units I bought, one spontaneously failed with a very loud hum and the smell of something melted. And this at a time when it was not being used and less than a week after its installation. I would hate to see how this device could fail if an actual ground fault occurs.
