How well does the controller work does it need to be pointed in a certain direction or Bluetooth control put close enough to it to work? Had a lot of problems with Similar lights dont want same thing to happen

Hello, this product is controlled by Bluetooth APP; There is no need to worry about the direction as long as you point to the lights; if you don't too close, you could stand in several meters away to control the lights.
