Yes you can put eggs in a waffle maker and they will turn out just fine.
I've used my waffle maker for making eggs and they come out great.
I use some Pam spray on the waffle maker to keep the eggs from sticking in the waffle make then I mix up eggs and pour them into the waffle maker.
The waffle maker makes great scrambled eggs and omelettes as well as brownies and much more.
Your waffle maker can be used for much more than making waffles and I use my waffle maker for making a variety of foods.
So they are pretty versatile and worth it to have a waffle maker.
