I bought 3-4 sets. They are good grates. slightly magnetic. They seem to be like the Honsgo and slightly longer so they fit more snug and don't slide around. I can't really say anything negative about them other than they are not 9mm. And for the price, I should probably buy a few more but I already have two or three boxes a day on my deck from Amazon. Burners, flavorizer bars, grates. etc...... I think the mail lady is getting a little ticked off, especially when she has to deliver a box with two sets of 13 bar 16 ga SS flavorizer bars.
