Are there any concerns/risks to using Watchtower? (alien.top)

Someone recommended it for keeping my containers up to date automatically. I checked out the repo and it seems too good to be true. It just updates your containers when a new image is available and everything just works out of the box? I'm a bit scared of just leaving it alone in case it might break something. The fact that it doesn't come with a gui also scares me a bit.

Does anyone here use it and can recommend it? Any horror stories?

I prefer to be there when container ar updated so that I can promptly fix anything that breaks.

I have 2 watchtower instances in a docker-compose, the first container 'watchtower-monitor' uses command: --monitor-only and warns me over gotify about the availability of updates but does not modify anything, the second 'watchtower-once' uses command: --run-once and it is usually inactive since it performs all updates once and than exits. When i am ready to update everything I just docker-compose start watchtower-once container to start the updates.
