Review on MegaCast Rotating Soldering Platform Solderite by Ikki Martini

I LOVE how it spins, just needs a quick lube. The shipping packaging was nice and neat. I DON'T LIKE that the solder block is beige with burn/mildew marks. I can't figure out if it's burn marks or mold? I was expecting a white block in the picture. Which is better for filming
