I bought this mini blow torch of Rothenberger Lighting of New Year's fireworks and can therefore only assess its function as zweckentfremdetes lighter. First of all it looks in my opinion, very good and is comfortable to hold. The nozzle is protected by an attached cover against contamination. The blow torch also has a Dauerflamme- and lock function. The size of the flame is infinitely adjustable. The first start-up went very smoothly. The filling with standard lighter gas succeeded thanks to good seal without the escape of gas. The laser flame ignites in about 9 out of 10 cases and is also in medium wind speeds of rarely. Gas consumption is contrary to my expectations fairly low. The extreme test on New Year's Eve has passed with flying colors the blow torch. The 400 °, which is to achieve the flame let capitulate fuses quickly. The flying Zündschnurteile have the nozzle surprisingly not clogged.
Conclusion: For New Year prefer to spend rather than vexed with cheap lighters this brand product.
