We had a similar one on a trip once. Did large trout on it OK. But I was thinking it's just a toy someone wanted to bring and justify buying. Packed small and flat, but heavy IMO.

While it did support a fresh fish nicely, ours was longer, not square. We didn't use it to cook with our pots and pans. We had stoves for that. It was a river trip so not much portaging. Still not for me, specially if portaging much. I'd just use a stove.

Hey if you like toys though, then go for it. They do work. Probably nice if you're only using it and cooking with wood. Smaller fire, smaller wood, concentrates heat, leave hatches and large saws at home.

Hey Ranger,
In the "Strictly Gear" forum I posted a review of the Slat Grill on June 22nd.
I like the grill quite a bit. The 4 inches is not much of a problem as I raised the height using rock.
Be careful as setting the duff afire is a real hazard.
I set my Whisper Lites and SlatGrill on a heavy cake pan.
I don't think you will be disappointed with the grill.

It works great with a stove or a stick fire. See if this link works for a picture.

I think it's nice for stability on bigger pans. That's WCPP LAke Trout in the pan.

Just a thought on the two different type of "slatgrills/options".
With the Arctic Fox type, you need some sort of windscreen IF you set-up somewhere besides a fire pit and the wind is an issue. IF you add a ash/snow pan, plus a windscreen, your adding extra weight/cost.
The other types have a windscreen built into design and can be oriented for maximum efficiency. With optional ash/snow pans, you could set them up anywhere.
Both have appeal, you just need to pick the one that fits your style the best and at least for me, which one allows more flexibility
