FRIENDLY REMINDER - When the water level is low the Elf will let you know with an audible “Water Low” warning letting you know that your Christmas tree is running low on water.
INTERACTIVE FEATURES - There is a lights up display on the front that lets you know when the “water is low” or “the battery is low”.
EASY TO USE - Simply adjust the sensor to the height of the tree stand and turn on the Elf. When the sensor detects that the water is low the Evergreen Elf will light up.
FITS ALL TREE STANDS - With the adjustable sensor the Evergreen Elf will reach to the end of any tree stand.
REDUCE THE RISK OF TREE FIRES - Now that you are on top of your Christmas tree’s water level, your tree will be more healthy and not as dry. Tree fires caused by an electrical spark are more dangerous when the tree is dried out and doesn’t have moisture.
