The great thing about a propane/butane or other torch is that it actually produces visible light. climatetorch.com didn't even remember to list that as a feature. Visible light can be useful. I'm not terribly impressed with their torch. (note the poor kid has had a 50% reduction in her carbon shoe print)
Does it even have a means to produce light on it? It may be a stick not a torch.
