Top rusted just sitting used once

I bought it for my son. He loves it. It was bigger than I expected. That’s a good thing!

1) Concrete - concrete doesn't melt, crumble or fall apart when exposed to the heat from a burning log. THIS UNIT DOES! 2) Poor air circulation - no way for air to come up through the bottom 3) Cheap Cheap Cheap - garbage. 4) Does not fit standard logs that you can purchase at any store - this is designed for lincoln logs.
