Just got it yesterday. It's a Sunflair portable solar cooker. Got it up to 275° F and boiled water yesterday and cooked turkey burgers today. I cooked the burgers for 2 hours from frozen. I bought the $80 irregular version but it has no abnormalities. I'm going to cook puerco con chili tomorrow which we usually cook in the crock pot all day anyway. Will report back tomorrow. There are a few YouTube videos if you want to look it up.folds flat for travel.
