We have been given this Bunsen burner and could use him at first really good. Every now and then we have a creme brulee refined tasty, we have used the torch about half a year, it filled up again. After six months, we wanted to use it again, because the gas was all. So buy a new gas, trying to fill up the burner, but unfortunately that did not work anymore. The little something still went in, came as a great tongue of flame out around the device, the front burner was therefore also defective. Only into the trash it!
