Sievert 3460K Turbo Roofing Propane Gas Blow Torch: build quality is excellent easy to use and am very happy. Delivery was super fast. The only problem I came a across was the customer service I asked them before purchasing about the connection as they differ from ireland to Britain and was assured the connection would suit Irish propane bottle, so when it did not I asked the same customer service guy for help and was ignored, so went to local hardware who advised me to cut off regulator and attach one he sold me this did not work. So went to gas dealer who reattached the one I cut off and gave me a bolt which attaches to original regulator and than bottle simple and easy. Customer service caused a lot of unnecessary hassle for me.
