Like many other reviews, the grids have rusted quite badly. The double sided design is unique and works very well. The pointed side produces great grill marks and food releases well (when they were not rusted). The cupped side also worked well, but that side rusted first and is completely unsalvageable. 

It’s unfortunate because I love cooking with cast iron, but my grills look like the photos posted here. Rusty and one bar has broken completely off. I seasoned the grill regularly and always keep a BK cover on it. Unfortunately it’s all past the warranty period.  

I have another grill at the cottage with the Baron stainless steel grids. Those ones look great, but you do not get the grill marks on your food and food sticks without an incredible amount of oil.  Would love a reliable cast iron grid.
