# I can't stop the device?
You can't stop the loggers. We use the “One button” operation and prohibit the “Stop” function.
Why?
From tracking records with our users in the early years, we noticed that a certain quantity of devices was started and immediately stopped by mistake.
We then decided to cancel the “Stop” function of the button by the end of 2019 to simplify the operation of the device.
This change proves effective and eliminates incidents of mistakenly/intentionally stopping the device before the shipment's arrival.
