Overall this is a very good pot stand. This is aluminum sheet metal that acts as a pot stand and complete pot wind screen.  This is a copy of the caldera pot stand I saw on the web. 

It is very sturdy and efficient.  The disadvantages are that it is hard to store because it is an arch when disassembled.  It is also very pot size dependent.  If the pot is much larger or smaller, a different one must be built.  I used binder clips or paper clips to provide a bit of adjustment.
