When I went to visit my grandmother’s house one day, I had a personal visit to the solar energy monitor, and said that its solar energy monitor worked well. I said that I had installed it at home. Thank you! If necessary, we are in contact, see the style is old, and into the house to do promotion, products also are not necessarily good, I later my grandmother said that is why, I told her high sell, sell solar energy monitor, said home solar monitoring quality is bad, fool me, the who, what, do you remember! When you see it, don’t give it to him. It’s a mess now, so make sure to ask when you open the door.
