They've had some significant failures. I think there was a thread on here with pictures posted of Smartplug melt downs.
As I recall, the failure was primarily with updating an existing power cord with Smartplug replacement plugs and receptacles. The plug end relies on plastic teeth to grip the power cord casing to keep the plug from twisting on the cord and shorting the wires. Also the thermal fusing didn't work when that occurred.
The factory molded Smartplug and cord didn't seem to have that problem, but it's a tad expensive.
