Query: Returned It - TWICE!

Based on positive reviews, I bought this waffle maker. The first thing I noticed was how cheap the adjustable setting slider was. Cheap and plastic. It's so loose, I couldn't even tell which setting it was on. Cooking was inconsistent as a result of this design flaw. After a few weeks, the slider broke.I exchanged it for another of the same model. This new one had the same design flaw. In addition, the new one kept burning waffles. I returned it, too.I will look for a different waffle maker.
