I bought a large size one, it can bake a turkey or 3 chickens. I have used it a total of 4 times. I should use it more but sometimes it is more work to get it out of the garage (no way it can fit on my counter, I use it outside on the counter to the window) than to just use my oven. The times I have used it, it was too hot to run the oven in the house. This year we never had a summer until this past monday. It's over 90 now.
