It works well. Spray before using. I use Krusteaz Light and Crispy Belgium Waffle Mix. It works really well. The reason I didn't give 5 stars...the little blue sensor button fell out and now it doesn't want to stay in. It's not the easiest to clean, but waffle makers aren't, no matter what.
We received the mini waffle maker as a Christmas present and immediately started using it. The grandkids were delighted to eat the waffles and scrambled eggs (yes, eggs cook great in it). Things cook in a jiffy! Great little product!
So far I love it! It was a Christmas gift, and I've made several batches so far. It's easy to use, easy to clean, and doesn't take up much space. My daughter loves all the shapes!
