Oh I don't know Rik, a small tent that one can Bergen and can have a fire or naked flame in is a great little tent.
Pretty tough and durable, easy to escape/exit if needed in the middle of the night, reasonably warm by accounts, cheap to buy, quick and easy to put up and take down and kind of a homage to a wigwam, if only in a minuscule way.
I like them, but like it's been said, it's a bit or a Marmite thing, you either love them or hate them.
I think it will be a fun shelter and I have seen a way to add an extra third poncho extending the width a little and a different door opening style.
I may also extend the height with a removable skirt similar to this design, perhaps a diagonal line from the apex instead of vertical as in this picture.
I think I will enjoy getting what I can from these shelters.
Main points for me are the ability to have a flamed warmth inside and the easy exit/escape route 360 degrees. That's why I sleep in a thermal suit and quilt.
Yes, they are two ex army ponchos that's been designed to make a shelter, there's no doubting or denying that, and I think that's what I like about these tents.
