By far the best - except the indicator lamps

This has the best internal and external construction. I’ve dozens of them at home. However, I have one feedback, which I know the manufacturer will not listen to.
The LED indicators are wired in series with only a single resistor and the resistor runs very close to its quarter watt rating. On top of it, the chosen gallium phosphide LED cannot tolerate reverse polarity that well. The result is predictable. Under continuous usage, the indicator LED ALWAYS FAILS after some months of use. If they add one more LED in reverse polarity or add another diode, the indicator will last forever.
Ironically, I like that the indicator fails! I like to not have bright lights at night while sleeping!!
I know that the surge protection works. Had a surge from our apartment backup power supply, anything connected without these plugs simply got fried and the ones that were plugged into these remained unaffected. Interestingly, after a surge, these plugs remained inoperational for about 5 minutes - indicating that the surge protection mechanism works.
