New Manholes for the iStill 2000/5000 Series?

Hi there!

I need your input and feedback here. We are considering putting glass manholes on the iStills 2000 and 5000. Both have a diameter of 40 centimeters. What do you think? Is this an improvement over the current model? Would you like to be able to look inside the boiler? Please let us know what you think!

Regards, Odin.
