This Frisbee is neat. It has a power on and off knob on the back that you just turn to power on! Then the fun happens. Different colors of light in various patterns come from the disc. Makes it easy to see at night so you have something to do as the sun goes down. The Frisbee itself is made heavy duty so to wont flex easy and be wobbly as you throw it. A sturdy disc that will fly far distances. To change the batteries you pull on the knob and replace the 2 3v button batteries. #RankboosterReview #Sponsored #CFTEch
