Most Useless:
Food Dehydrator
Waffle Iron (the plates aren't removable, making it a pain in the patootie to clean)
Sandwich Maker (same reason as above)
Stick Blender (used once!)
Vacuum Sealer
Good China (My mom bought the set for me, but it's not dishwasher safe, making it very impractical. Never used it.)
Coffee Cups (DH rarely drinks coffee; I don't drink it at all)
Blender
Most Useful:
KitchenAid Mixer
Vidalia Chop Wizard (love it for chopping onions)
Juicer (even though it's a pain to clean the filter screen thingy)
Microwave Popcorn Bowl
Jar Opener
Wisks
Small Coffee Pot (I use it to make tea!
)
Cast Iron Skillet
Parchment Paper (love it for baking cookies, biscuits, fish sticks, french fries, etc.)
Dishwasher!!!!! (I *loathe* hand-washing dishes! I would rather clean the toilet! LOL!)
