I've had it for over a year. I'm creating a small electronic worm and it's a very valuable tool for all kinds of work on my desktop. I've recently started using it with one of the nozzles, which provides a more concentrated airflow, and I've noticed that the unit with the nozzle doesn't go into cooling mode when you put it on the stand. If you remove the handpiece and put the pen on the stand, the device enters the cooling mode correctly. I can't believe this is an oversight on a very good tool, so maybe I'm mistyping the tip.
