I use these burners to ignite my hookah natural charcoal. I've gotten even with friends and can test multiple bisther found no better. He makes a really good heat and skin a coal in a few minutes. With bamboo charcoal as the nature Bamboochas rich even 30 seconds. The life is for this simple job at with approximately 1 year per cartridge. But I must say that the extremely tough Cocobricos considerably longer and, therefore, a new cartridge needs to be bought quickly. The processing of the Bunsen burner head is very good. Through a small adjustable ring can switch between normally and soldering flame. However, this should be done in Setting the first 30 seconds of use, as this ring then is so hot that you can burn yourself. To Halrbarkeit I can say that I now, 3 years with this more times a week working and he still had his service, without the smallest little problems, performs.
For me, this burner is therefore related to the coal or light a barbecue just buy it. For soldering behavior unfortunately I can not say much, so I give the burner in the coal to light a 5 star rating.
