Quoted from ZMeny:I have heard people experiencing a plop down one step but never usually three. I’ve never had any issue with carpeted steps. If it went down three steps then the unit was leaned back too much and the sliders slid it down like a typical handtruck
First time I used it I skipped the last 2 or 3 steps exactly for that reason. It was leaned too far back. The game was still in box so there was some protection anyway.
I've used it at a friend's house with thick carpet AND turning stairs. No issue at all. The key is to keep vertical enough to ensure a good grip.
