I'll read it in more detail and check out the different bases for more

Obviously, it is not completely invisible, BUT at the same time I think that it is very seldom a person who is not aware of that you have a system would begin to inspect and check for example the front edge and would they see that there is something in the front I do not think many would understand that there is a system. It is so "unusual" yet...

But correct me if I'm wrong ...?
