It fits on the grill easily however it sits high above the flame which takes your food a long time heat up. I think it might just be better to sit your pot on the grill it comes with because that grill traps the heat where as this rack doesn’t hold the heat it just escapes around it.
Most grills dont have something like this to put a pot on. This is great to keep everything together. Time will tell on how long it will last. Just keep it clean and dry and I assume it should last many years.
