Those three light cubes don't work..
I used a non contact voltage tester, and on our outdoor outlets, it only beeps when inserted in the hot slot, but the house ones beep in close proximity to the outlet, and one outlet in the house don't beep at all even if you inserted the tip in the hot slot ,but the light and phone work in it.
That is why I,m wondering if there miss wired and we can,t detect it,will it destroy your computer, I,m aware it is dangerous.
