Update 4/25/2015:
The sandwich maker is great.
It should be noted, not to pack too much cheese in the toast. Lot Recommendation example for the cheese is in the description.
I clean the heating plates after each toast with a damp cloth or soft sponge. If necessary, I put the heating plates in the sink to soften the dirt.
Only now and then I put the heating plates in the dishwasher.
