I actually had similar frustrations as member Nonprophet. I did lots of reading and asked a few questions. I finally drilled 2 additional holes in the dog house. I have been very happy with the results. I figured I could always plug them up if I was not happy.
Prior to modifying the dog house, the stove was starved for air. The air control lever made no difference. Once I modified the doghouse, the fire would respond to different air control settings AND the startup seemed a little easier. I still had to leave the door cracked for 5- 10 minutes.
Overall I like the stove. Because I am a member here, I do tend to look at other stoves from time to time. However, I have no serious plans to replace the Oslo. My advice to the OP: Burn the stove and see how it does. You may be talking about an issue that may or may not apply to your setup. Time will tell!
