The wifes vest deployed whilst riding pillion with me. No bumps jumps or stupid pot holes and my vest was ok.
We contacted the supplier who took back the vest and sent away for tests. A.S. say they found no reason for it to deploy and are sending back recharged. (still under warrenty).
Great after service with Infinty, York.
periodically check the app for firmware updates to the vest ECU. I just got a notification last week of one. I think they collect log data and do running improvements in deploy algorithms
