Product review (5 stars): No one has noticed the difference.
About 5 months ago my husband and I did a top to bottom remodel of our kitchen.  Our dishwasher still worked great and we wanted to save a little money so for $20 it was worth a try.  WOW!  We have been showing off our kitchen to friends and family ever since and not a single person has noticed that the dishwasher wasn't stainless.  Keep in mind our dishwasher is about 8 inches from our real stainless fridge so there is a real side by side comparison.  I can tell the difference because the magnet is slightly lighter than the real stainless but I KNOW it's a magnet so it might be psychological.  The magnet is also crazy strong, has never fallen off, and is cleaned the same as all of my other appliances.  You can't beat this cost or quality of this product.  Just a side note though.  Make sure to fully clean and remove any dirt or dust before applying the magnet. If dirt gets trapped under the magnet you can see a tiny bump if you look VERY closely.  Im pretty sure it could be wiped away but I haven't tried yet.
