how do you use them and clean them, i brought 3 packs of 4, and use 8 of them and some of them were sticking, and i am buying a egg cooker.

Use whatever method is recommended on the package they came in. I'm sure gentle scrubbing or the dishwasher would be fine. I don't use them, but hubby makes scrambled eggs in the microwave every morning and they always stick to the bowl. A little non-stick spray helps a lot.

it taste great, i just had a hard time cleaning them.
