Ninja FlexFlame Upgrades Premium Half Griddle, Professional-Grade Carbon Steel Griddle Plate with Grease Drain, Rust-Resistant, Combo Cook, Even Heat, Compatible with Ninja FlexFlame, XSKHLFGRIDLE

It's a great accessory but way overpriced.The good:+ Thick, heavy duty cast iron+ Option to have the drain hole on either side+ Fits well and it's a nice option if you want to use both the grill side and the griddle at the same time+ Making fajitas, roasting potatoes while making steak, etc. is really convenientThe not so good- Price. You can buy a similar griddle add on that goes over your existing grates for about 25% of the cost of this pieceIf you want the branded offering and something that is made well and will fit perfectly into your Flexflame grill and don't mind paying for the privilege, this is a great upgrade.
