I have one that I started using a couple years ago. Overall it works great for what I need but there are a couple caveats-#1 the thing is heavy, #2 as someone said they are dang expensive and #3 when I got mine one of the rods at the top of the right wing had come loose from the plastic and comes out if the wing is open and unsupported. Not sure how common that is but does require me to support it somehow, normally on a camp table. I carry all the eating and prep items including spices and condiments in the bottom and a Coleman dual fuel stove on top-the smaller one as the Powerhouse 414 is too big.
At the end of the day I am happy with it but cannot say that it was a game changer for me vs. stacking stuff in an alubox or something similar.
