Curious to hear your reviews. https://smartplug.com/
When the SP was redesigned, the over temperature circuit breaker was eliminated.
The overtemp feature was the main reason to buy one. Without it I'm not sure if it's that much of an improvement.
Marincos new EEL cord with the jaw clamp design is similar to the SP without having to replace the inlet fitting.
For what it's worth, I think the IEC pin and sleeve plugs are the best of all, used pretty much everywhere in the world except North America.
I was not familiar with them. They do look really solid with lots of contact area.
We have been using the Marinco and Hubbel 30 amp fittings for nearly 40 years without problems. Not even burn marks on the spades. The key is to keep the plugs clean and the locking ring tight. Shoot it with a temperature gun when running close to 30 amps and check the temp of the fitting. If it is hot, time to clean or replace the plug or inlet.
Without the thermal cutoff, the improvement offered by Smart Plug is not worth the extra expense.
