For safety, Coleman is superior. I've owned other brands, and I cook outside on my covered porch every day. Fish, cauliflower, seared high temp steak, etc. Stuff that would smell up the inside of our house. So I've had other brands malfunction, especially at low outside temps. I wouldn't recommend doing any technical repair work on the valves, like another reviewer accomplished. Needless to say, gas stoves can be dangerous . So don't fool around with valve repair. Flame adjusting from high to very low is best done by first, turning off the burner, then just barely turning it back on again and relighting it , of course. The only major change I'd strongly recommend ; probably or any lightweight camp stove ; is to attach it to another surface for stability. A heavy pot can cause the stove to move, if you move the pot around while cooking. For safety, I'd recommend permanently attaching it to a 3\4 " plywood, about 4" wider this all directions, by long sheetrock screws around the outside ( tightly close to the stove--not drilled through any metal)  My stove is attached in this way to an aluminum-covered , wooden table, and the table is also screwed to the porch floor. I also have a grill-tank, not the small cannisters, as the gas supply, and have done so for many years ; standard hardware is available to make the conversion.
