My Love does all the cooking in our home and was dissatisfied with the cookware we had been using. He found these and really wanted to try them out, so I bought them. He LOVES them, and I love the cleanup! I did see some of the negative reviews regarding clean up, food sticking, etc but we have other Ninja products that haven't failed us and wanted to give them a try.
What we found, is following the instructions by preheating the pans, using fat such as lard or tallow fat, even butter kept the food from sticking. It doesn't take much fat, just a little bit will do.
Clean up is easier than anything I've cleaned in all my 60 years. I let them cool down (just as the instructions recommend) then add water with a drop of soap and let soak. After they've soaked awhile, I empty out the dirty water, rinse, wipe (no scrubbing required) with a poly mesh scrubber and then dry.
