Mine leaks a little smoke around the door and at various spots in the joints, but it is still relatively new (4 cooks). If I am using the IQUE and keeping the bottom vents closed, I can close the top vent and knock the temp down like a rock, so I'm not real concerned about a few small leaks. When I'm not using it, I keep a bungee cord around the door to hold it against the side of the cooker and it seems to be getting better in that regard. The big one uses a lot of fuel compared to the 18.5 I had before.
