Good in Theory. Not so much in application.
I did not find much use for the bio gas system. After filling it up I could not find a suitable place to use it. So it was just sitting. This is more my fault than theirs that I did not find a good place at first. But this year once I created the space and built a setting for the system upon refilling the bag I noticed there were many holes and the seams seemed to be leaking as well. I felt very disappointed, because we would have done much better putting out money into a regular septic tank that would not be so easily harmed by weather and punctures. It seems we are out of warranty now that we finally decided to use the system. So we are very disappointed. Maybe the team can contact is and show us how to patch our faulty dispenser tank bag. All in all it seems like a good idea in theory but mainly in theory. If we can get the bag replaced than maybe we can have a different view but all in all we expect the bag to be much more durable considering it's holding excrement and feces.
