I was given the set for Christmas. Although pre-seasoned, I'd still recommend seasoning it more and using it indoors, as well, to build up the seasoning. The 4L dutch oven is fine for meals for around 4 people, but you'd want bigger if you were catering for 6-8. Bread works well. For anyone who had the bread at the Moot Hangi last week - that was done in a 4L oven.
Price-wise, the set was the same as the individual components, but you get the wooden box, in effect, free. As has been noted, the box isn't that sturdy and mine arrived with some of the screws pulled out of the wood. Credit due, they did give me a refund on the postage as compensation for me having to fit a few longer woodscrews myself.
Their tripod is 'OK', but I'd prefer one that was a bit taller. You can't raise the dutch oven up that high on the chain before it fouls on the tripod legs.
