Fast delivery. Well packaged. No apparent problems. For the rest, I can say with some humor: difficult to know in advance how this product will react if needed .... One downside, however: this is one more device with two LEDs that are always on . It would be better with a switch that allows to cut everything, including the lights. Our accommodations are increasingly "equipped" these lights that operate 24 out of 24, certainly no big impact on our personal expenses but not insignificant environmental when we see that this is happening in the world ... facilemnt and could be avoided.
