this is actually a good example of how a more detailed issue will have a higher chance to be addressed. I don't know what information that's your previous report is lacking, but the video certainly give more information that the maintainer can pinpoint the cause and act on it. The ability to pinpoint the cause from the report is a godsent for maintainers, it drastically reduce the time to investigate the cause, thus able to act immediately.

Some of the information in this can may be:

* how "slow" exactly the process is related with normal behavior. If it's just said "slow" on previous report, it's easy to be dismissed

* the dispenser's behavior, such as if the water flow is consistently low volume or clogged intermittently, or if the dispenser is struggling to fetch from water source, etc
