Yes, I could use my sink as a lid holder, but the sink is on the opposite side of the kitchen, seven steps away, so that's not very efficient or practical.

I could put the lid upside down on a towel on the counter top, but the counter top on either side of my stove is just 12 inches wide, so the entire counter top becomes a single-use kitchen gadget if I want to use it as a place for holding a lid. That's not very efficient, either.

With this lid holder, I can put the lid right there on the counter next to the stove and still have lots of room for seasonings, a plate, etc.
