Time operation: Very easy.
The manual is clear and the 80/125 mic switcher obvious. The stench was limited, I had feared worse.
It is warned, otherwise the device can wait when switching 30 seconds as damaged. Whether this actually happened I have not tried.
Use: Easy
The device needs to come up to operating temperature for a few minutes to. After that I was able to send seven films in a row, without the device has indicated that it needs a break. With more films I have not tested it, but it seems a Uninterrupted operation to be possible.
The engine sounds are very quiet. I had no blisters and the device pushes the finished film goes far enough that the end is not in danger, to melt.
