I brought this dough roller several years ago but only used it three times. The first time I used it there was some smoke coming from the rollers but that stopped. I guess I should have returned it then as now their is small black flakes like a rubber gasket material coming from the rollers into the dough I was rolling. I took it apart and found a small black gasket all chewed up however I can't locate any replacement parts. This item isn't cheap and should have lasted much longer.
