Defective Light, (IgoGolf VA)07/12/2018
One of four lights is defective and wont work.
Would not light up, (CStec WA)07/09/2018
Received defective. Would not light up even after charging them in the sun with the battery provided and another battery. Only tried out the green one so I can't speak for the other 3 colors but since the one didn't work wasn't going to take my time to test the others. Returned for refund.
