Input:
I received these as a gift, and after little more than a year, they're completely unusable. After using them, on average, weekly for a year, they stick horribly, no matter the recipe, and can't be cleaned without soaking and 20 minutes of scrubbing.

I put them in the recycling bin tonight and will look for an alternative. A well-seasoned muffin pan produces popovers that aren't as tall, but at least they come right out.

Most worrisome of all, I reached out to the company, through its website, a few months ago about any suggestions on how to prevent sticking, and received no response at all.

This is the last time I'll buy a Chicago Metallic product.
