Actually, I’ve only had one toaster “with a brain,”
****************************************************
I had one toaster advertised as having a “bread brain” , that one worded fine ... my problem seems to always be with the electromagnet hold down .. they don’t shield them from crumbs and they fail to stay down...
Sorry I turned this into a toaster thread. LOL!
Graphene technology will probably help with more than toasters. And if you have a method of protecting the hold down from crumbs, you may be onto a marketing niche there!
