For those that cannot access the page, I am reposting below.
ATTENTION SELFIE STICK CUSTOMERS!!!
If you find that the battery does not fit well or the remote isn't working correctly, please see the pics below. There is a small metal pin that may be protruding far out in the battery compartment. If you push that small pin IN just a tad, it helps the battery fit in the spot better and once in place, the light should come on. You can then connect your phone to the remote via bluetooth.
The name of the connection is AB SHUTTER 3 or something similar.
Let me know if you are still having problems. thank you!
