> because I am ... most likely to have a functional dishwasher and even if yours is better I am not going to buy one more. Break the population into groups: 1. Have a working dishwasher / don't need one 2. Old dishwasher is failing, looking for a new one 3. Just bought a new dishwasher, it works great 4. Just bought a new dishwasher, going to return it I suspect group 4 is who they're targeting.
