This item can be used in a covered outdoor setting, but it should be brought indoors during bad weather. For year-round display, we recommend using it indoors. 

Ensure that you have your batteries inserted with the correct polarity (-/+), that your prop is turned on, and that there are no obstructions in front of the motion sensor. If your prop still will not activate, please do not hesitate to contact support@tekkytoys.com and we will assist you.
