Product review (5 stars): Very Nice - Must Season
Now that I have the griddle, I have a use for that darn middle burner.  Unlike others, I used a pair of pliers to remove the feet when I got it, because the original grates were already missing them and I wanted to maintain the slide across grate surfaces.  I pull the grates on and off every single day for cleaning and they have not damaged the finish on the stove, in any way, in my couple years of using it.  So, I don't need the feet.

My husband decided to use it before I had a chance to season it.  YES, it does stick, but any unseasoned cast iron cookware will do so.  After seasoning it, I simply preheat the griddle, apply cooking spray, and sear away (vegetables, meat patties).  I've heated flatbreads, seared veggies, cooked burgers, and unlike most 'pans', I can sear my foods and get a perfect crispy brown outside, and have yet to burn anything, despite leaving it longer than I should.

I have never removed it from the stove, or used any sort of soap to clean it.  Simply scrape any seared residues with a plastic spatula, scrub with a wet cloth or plastic brush, and wipe it dry, right there on the stove.

I do notice that the heat doesn't distribute evenly, but I blame the burner more than the griddle.  It works for me because it allows me to move foods around during cooking to adjust their heat, or to cook different foods at different heats on one pan, just like I would do on a grill.

I am very happy with this purchase, and only disappointed that I didn't get one when I bought my stove.
