Don't risk your money! First Andy Jiang sent a good product. On my next order he sent some defective panels. Since I received them they started to fail. First he said it was a configuration, after only a month of use the panels started to show stains! On all the panels. First on one panel there were stripes as I show in the photos, as the days went by, the panels started to get stains! And he doesn't want to take responsibility! Don't risk your money, avoid the trouble of filing a dispute on Alibaba, since Alibaba gives more priority to sellers than to buyers! I have all the necessary evidence

Great service and good product
