I have used mine a lot since I got it, both in my garden here and on long canoe trips. I have, by and large, only good things to say about it. The one criticism would be that it can be a bit fiddley to put together, especially if your hands are cold. It has kept me warm in windy/wet conditions just outside my tent and I have used all sorts of fuel in it, wood/bark/cones/charcoal, even coal and it has always served me well. One of its great advantages is that it uses less fuel than a fire ir some of the larger stoves I've used.
It is a bit on the heavy side to carry around, being make of stainless steel, so it is more suited to a base/canoe or car camping situation than backpacking. I have used it most often with the grid top, rather than the solid top and chimney as I feel the heat gets out and to your cooking more easily. Derek at Woodland Edge assure me that all parts are replaceable should you loose any.
Is it worth the money? That's a question that's difficult to answer. For me the answer is yes as I think I will get my money's worth out of it as I use it a lot. If you only intend to use it on high days and holidays then possibly not. However, for me, it certainly does what it says on the tin.
Hope this reply helps.
