You gotta make sure you know what you're criticizing before you criticize it. They give you two months to reactive your subscription, and even then if you happen to be on a ride when the subscription ends, it doesn't deactivate the airbag. It won't just stop working in the middle of nowhere because it doesn't have a connection. The system to trigger the airbag is only connected to the system that checks the subscription in that when you turn the vest on pre-ride, the latter is what turns on the former. After you turn on the vest, it cannot deactivate the airbag until the vest is turned off and back on again.

Subscriptions are still absolutely shit, but you're making assumptions about this product that aren't true.
