I purchased my first one which ran for a few hours then the regulator stuck at closed and no gas would release from the jets. I received a replacement. I used it for less than thirty minutes and when I tried to use it again the entire stove went on fire. After pouring water on it, to extinguish the flames, I found that the regulator was leaking gas and would not close. Both of the stoves were faulty and dangerous: One of them became unuseable in a short period of time and the other failed in a dangerous manner after only thirty minutes use. I recommend that people do not buy rapijet stoves
