4.7 stars is pretty good but I always read the one star reviews and they're not so good.
Also, I would want a thick griddle to cook on - to eliminate hot spots. Not sure how thick that griddle is. The griddle I use is 3/8 inch thick commercial cast aluminum - too bad they don't make them anymore.
Finally, I love my propane range in the kitchen because you can SEE the flame. I think most chefs own gas ranges in their kitchens. But I know from cooking on camp stoves that it's really hard to see the flame when you're using a griddle on it outside. And then there's the wind problem - you want to cook low to give you control over the cook, but a gust of wind comes along and blows out your flame. So you light it and increase the flame so it will stop blowing out and then your food over-cooks.
Good luck
