What can I say; that thing blows really hot air. I got my first device and had problems with a soldering iron that didn't want to work very well. The replacement sent by Amazon worked perfectly. The machine comes with heating elements for soldering iron and hot air. I suspect the heating element on the first unit's iron was faulty, but since I had just received it I decided it wasn't my job to fix it for them and exchanged it for a new unit. I've used the device quite a bit and it worked great. Personally, I'm not a fan of the built-in extractor and plan on removing it from the handle. I made a custom flue and prefer not to have any extra weight on the handle.
