Are smokeless fire pits actually smokeless?

Across the reviewers we read, the consensus is 'low-smoke,' not zero-smoke. Specialist threads on r/landscaping and r/SoloStove repeatedly explain that these pits smoke while heating up, then burn cleaner once secondary combustion kicks in—and that dry, seasoned wood is essential. Reviewers stress you'll still smell some smoke at startup and in windy conditions.
