I absolutely love my Blackstone 22" griddle. This stand - not so much. Admittedly, when it is set up and stable, it works well. But the issue is with the legs and the method utilized to adjust and stabilize them. I can't help but think there must be a better way to engineer a system besides simply screwing a post into a smooth metal leg to provide the necessary friction. I've used my stand for about two years now for camping trips and it has a long string of screw indentations in each leg - probably not sustainable in the long run. 
If the leg stabilization/adjustment system could be re-engineered, this would be an ideal accessory for the griddle. Until that happens, it's still the best option for your Blackstone griddle.
