The wallpaper runs flawlessly on my tablet (Asus Memo Pad) and also charged the battery excessively. The settings are more than diverse, the background image can be adjusted according to the time of day, the lighting on the trees can be turned on and off and the color of the lighting is just as easy to adjust. In addition, can be activated beautiful northern lights and the intensity of snowfall is as adaptable as the size and appearance of snowflakes. As a special you can occasionally watch a falling falling star which again gives the atmosphere a little bit extra.
There is a mode that allows the wallpaper automatically adjusts the current time of day, but you can also adjust its preferred embodiments permanently, so that is always the night, day or twilight background displayed.
For me, this is considered wonderful definitely one of the best wallpapers and not just at Christmas time.
