King Kooker dual burner

Has anyone tried one of these King Kooker Dual burners? I know they must be a bit flimsy for the price, but can they hold 25 gallon kettles and is it easy to control the mash temp? Is their a better alternative? Thank you.

My brew buddy has this and has used it for a while with no complaints. I may get one when my dual camping burner stove gives out.
