The device works very well. I use It with WS2811 garland. Inside: Controller, instruction manual, 3pin tail with connector (red (+5V) - green (Data) - white (Ground) ). The recommended control software called "LED Shop" located in the "android play market" also works well. If you disconnected of wi-fi, the controller works with last selected pattern.
SP107E has a better variety of sequences than the 105 and 110. For the price - a nice and easy to use controller.
