I am quite pleased with mine. Initially I had the flare up problem, but it was successfully corrected by sealing the bottom seam with JB Weld. Preheating was a problem when the stove was not completely filled (~ 1.5 oz.). It takes about 0.5 ounce of alcohol to boil a 10 ounce cup of water (Lid and windscreen). To preheat with less than a full stove I place a BB or pebble over the center (fill) hole so that more alcohol is retained in the center. A bottle cap containing a little alcohol may be placed beneath the Triad to preheat it as well. I am more comfortable with the strength of the Triad verses my Pepsi can version, and it only weighs 1 ounce (vs 0.5 oz. for the Pepsi can). Great little stove IMHO.
