After I got it, I washed it with soap once then I seasoned it 3 times in the oven, 1 hour each time. I grilled steak and veggies on it with no sticking. Nice smoked flavor but not identical to an actual grill. Definitely get this over a nonstick grill.
I appreciate that compared to a regular cast iron pan, this one lets you really char the food without burning the entire surface. Works amazingly with vegetables and it makes good roasted red peppers as well.
Cleaning is a lot easier than I expected. I pour some boiling water on the grill then use a nylon brush to scrub everything off. You don't need to use much pressure. Then empty that and possibly give it another scrub with kosher salt and a little oil to get rid of some browning. Lastly, rinse everything out and dry it on a flame. Then season it once quickly.
