I'm going to preface this review by saying that I've never had a problem with any Trangia gear that I have purchased. I got one of the 25 cook sets, and I absolutely LOVE it. I have used it camping, I have used it tailgating, and I have used it during power outages when our electric stove would not work. You can really do much more cooking with it than you would think, and it has been a true blessing during power outages. I decided to buy the winter attachment to add to my collection, and while it seems just as durable as any other piece of Trangia gear I own, I really do question whether it is truly needed. I have never had an issue getting one of the burners to light in freezing temps when I've warmed it up through body heat, or had it snuggly packed away, or just used a lighter underneath it for a few seconds, but I also have never used one of these consistently in sub-zero temps either. So to anybody contemplating on purchasing one of these, I would advise you to consider your actual uses. For 3 season weekend camping, you probably don't need to buy this. If you live in Alaska or plan to climb Mt. Everest or something, then you may want to consider it I guess. If you just really like Trangia stuff, then you may want to just go ahead and buy it. You are getting a plate/pot cover, the burner, and the winter attachment for not too much more than what the burner itself costs. Having two burners will also expand your cooking capabilities as well.
