Just got myself a Chinese BRS-12 for about 55$. It does not run well on kerosene but on petrol/gasoline it burns with a strong pure blue flame. For the price of this stove I wouldn't expect so much quality, but it is not so bad. The jet is a bit off center and I had to fix the pressure release valve on the tank lid which was letting all the pressure out. The pump cup is not made of leather, but it is formed as a leather pump cup which you can see on my pictures. I am dedicating this stove to snow-melting since it boiled a liter of water in 02:38 minutes. The tank also holds 4,5DL which keeps the stove running on full throttle for about 3,5 hours. It is a roarer, so it makes about as much noise as a 111.
