I don't know them by this name, but I've seen them in stores. They're Cdn$140 at Canadian Tire.
Looks cool, but makes no sense to me. It seems bulky and (without the lid) not very functional, although really quick to set up. They also seem expensive for a very small (105 sq in strangely shaped) 7400 BTU/hr grill - for exactly the same price in the same store you can have a
Porta Chef with over twice the grill area and 20,000 BTU/hr of burner output. The Porta Chef is obviously bulkier and heavier, but there are all sorts of choices in between.
The grills which are the size and shape of the typical portable
propane stove (such as a
Coleman) look like a more useful portable cooking area to me, but I haven't tried one (just regular barbeque style units - including a Porta Chef).
