Speaking was to buy a set of solar lights on their website (fvtled/com) two weeks ago, a group of 20 is 200 yuan, my house has a courtyard, but the night is very dark, so buy them, their The solar light can be charged automatically and will automatically turn on at night. You can use your phone to control the color of the lights, but after a week, the WiFi of the phone can't be controlled, I contacted them. They called the engineer to repair it. It turned out that my own mobile phone did not open appWiFi control, which is my personal reason. So thank you fvtled they can come over and help! !
