Works very well overall as far as I can tell, no mechanical or electronic issues. It appears to suck smoke out of the air and works both vertically and horizontally, but as far as I can tell it's a Hakko FA-400 with a modified icon (or even another one with no insignia), save for the presence of empty seats on stickers and even on product packaging where the Hakko logo would normally be. It works reliably, as you'd expect from Hakko, but it's obviously an "overnight run" product. That being said, at a fraction of the price of the Hakko model, it's very good value if you're on a budget.
