While i like everything. Let's see how long it takes. Aa batteries 2 pcs are not included. It came suddenly quickly. I did not communicate with the seller. When turned on, there is a thin sound. But i'm not annoyed. Three modes of glow: constant, variable, frequent. The color is bright, the photo does not transmit it. I bought to walk in the evenings with a dog, because in our village it is bad with lighting. I recommend to buy.
