Geoman knows customer service:
No worries, we'll take care of you. The colder weather has affected run-times.
On another note, run the battery to empty and fully charge for 6 hours or more to reset the programming. Retry the run-time. Keep the battery warm when testing outside in your jersey front, etc... Advise.
Thank you!!! We appreciate your support very much.
Best regards,
GeoMan
