To those who have served juror duty, can you tell me about it?

In the Netherlands, as opposed to the United States, there is no juror justice system.
In On the case with Paula Zahn, which I am currently watching, a case is being shown where a convicted murderer got a second trial.
The jurors were deliberating for days and when they came out of their meeting into the court they were all visualy distraught.
They convicted the guy for the second time: guilty.
My questions if you feel like answering, I have no idea if this is too personal or not: Have you ever had to fullfill you juror duty, and if so, in what kind of case?
What was the conclusion and did you agree with the outcome?
Was it hard for you to decide on someone’s future and was it an experience that has left an impression?
