I got this portable BBQ set a while back. This is one of the smallest and compact BBQ set I have seen. This is great for backpackers and bikers and it doesn't take up space. If you wish to reduce weight further, just leave the Fire-bowl at home. Alone the grill weighs around 560gm.
It is made of Stainless Steel material and cleaning the grill is rather easy as it provide a cleaning groove to scrap out the food that is stuck to the grill.
Don't expect to feed 10 people with this grill but I had managed to BBQ for 7 people, though it did take some time. Well ......what the heck, we had the whole night camping so we got all the time. The Grill and fire-bowl are sold separately
