They say that you have to keep a little mystery in your relationship if you're going to make it work. Sometimes that means dressing up, role playing, or making love with the lights off. It keeps everyone guessing. I think that's also true for your toast. You want to keep a little mystery with your toasty bread. That's where the fun is. Will the toast burn? Will I let it out too early, or too late? It's a dance. It's crucial for your healthy relationship with toast.
This is very cool though. Perfect toast every time. I have no clue what it is that powers this device though. Does the glass toast it? I'm terrified of that for some reason. It's like when lasers get used in cooking. You can't trust lasers or hot glass.
