Recently purchased a Bushcraft Essential Bushbox ultralight to use with an Esbit stove. I have only used few times but so far happy with it. I have a relatively narrow 750 ml pot and with the alcohol stove the flames lick the sides of the pot and it's not as efficient as with a larger diameter pot. An advantage of the Bushbox is that you can purchase additional ash-tray to put at the bottom and then use it with solid fuel tablets or even make your own fire with twigs (if location and conditions are appropriate to do so safely). If it is windy, you definitely need some sort of windscreen.
Like the Tangria triangle you can carry it flat, takes 1 minute to assemble and weights 70 grs.
Since this is not designed especifically to use with alcohol stove, there is a trick to put out the flame: just remove the inner rubber seal of the stove's lid and slide it through the open side panel to place it on top of the stove.
