Hi Dave,
I'm glad you like it. I think they're super duper.

I don't know why I didn't have one before.

I didn't think to warn about the bowl.

They are very heavy although I find if I use a small and shallow baking dish instead of just using the racks it's very easy cleaning. On mine it says you can place aluminium foil on the base to keep it clean.

Enjoy! Just don't look at the light for too long. It's blinding and your eyes can do without that.
