I have to say that I haven't had any problems with the grate clogging. I fill it two thirds full and get around thirty five minutes of a burn. More than enough for a brew or a one pot meal. I have burned foraged fuel in the shape of twigs, leaves, sheeps wool and pine cones. The pine cones burned very well indeed and spitted and cracked away nicely. I use white block fire lighters to start it and carry a couple of disposable fag lighters.
The whole lot comes in a litle draw string pouch, measuring around six inches by eight.
I think I meant the cat litter due to small size covers the base not allowing air to rise thru the grill holes. But you are right a very useful simple device that works well and packs small and you can put some of the fuel inside the packed thing for carrying.
