Delicate device The gas orifice nozzle is very thin and I was only able to use the torch once. After that it was impossible to open the mouthpiece. I no longer use it and will find someone who is in retail and can fix it to give them a new way to use it. - I do not use the "return" option of the goods because I live very far from the USA and the transport is more expensive than buying new in my local market.
