Three stars for the poor mantel installation.  The top of my fuel stem has two sharp barbs on the ends which point up.  Installation of the mantel was difficult to avoid catching the netting on the barbs.  The mantel does not have a spring or tie strings which would allow you to enlarge the bottom hole.  I used needle nose pliers to stretch the hole wider so I could work the mantel past the barbs.  I installed two mantels, the first was connected to the small grooves at the top and bottom of the fuel stem.  This produced very low light.  The second mantel was in a more marshmellow shape and will produce a much brighter light.  The light is not half of a double mantel lantern, so don't expect that.
Everything else from other reviews is true, packs small, light weight, top gets hot, but the installation of the mantels is poor and that is why it only gets five stars.
