Stationed outdoors and works intermittently - cameras go dead for 18-48 hours then come back online on their own with battery charge losing 25-35% within this blackout period. Ambient temperature was only down to -10 DegC so should not affect functionality but it appears it did. Batteries advertised to last up to 6 months but I only get 1-2 weeks max. Considering a return as I feel ripped off. ———————–——————————————— Update on Nov. 19, 2019: After running 2 cams thoroughly for 27 days straight since product launch, I contacted Ring customer care and they checked logs which exposed random reboot cycles hence the blackouts and horrible battery life I was experiencing. Was advised to return the cameras as there's no known fix, returning to Amazon. Save yourself the grief and get a better product, reconsidering my entire Ring security system and Doorbell pro that I've invested almost $1k on at this point.
