Saw this and had to get one.
Says it's a cooker and a warmer, but I suspect I'll use it just keeping food (pulled pork, brisket, etc.) warm for poker or other gatherings.
The trays and lids are sold separately from the unit.
You can get a single tray/lid, double tray/lid of triple tray/lid. I got the double obviously. not bad price I think, about $155 for all with shipping included.
Thought about getting triple as well, but decided to hold off, since wife reminded me we have a triple crockpot type thing for keeping smaller amounts warm.
I need to take an inventory of "everything" and make it mandatory I look at it before I buy something to avoid buying same thing twice. haha
