I'm in 2nd place for this model. I haven't opened or used it for the first 30 days so I'm not sure if it won't work like it used to (within 40 minutes) if I can send it back. but I hope so! I finally got to use it the other day and we hit the 40 minute mark, but as this is technically my 4th soldering iron I've received (the first 3 were defective) I won't breathe a sigh of relief. a while. First I went for the lower model, two returns later I ordered this one. This one failed and now I hope this replacement lasts a long time otherwise I'll have to save money to buy an industrial model!
