I bought the ten pack of these at least 6 months ago and have been waiting for the right weather. Our wildlands have a high fire risk so I wanted to wait for a decent snow which has hardly come this winter. We finally got a good snow cover and the wind died down. We launched the lanterns last night. I held them over a propane-fired radiant heater (a Mr. Heater MH12T) and I would recommend a pre-heat source of some kind so the wax/paper fuel onboard the lantern doesn't have to do all the initial heat-up.A lantern like this has to be lightweight so the design must be minimalist. They could probably be improved with a more innovative fuel to add power without adding weight or expense. The paper design and construction is very good.I would prefer a biodegradable fuel holder rather than the metal wire. I think it could be done with reeds, bamboo, rattan, or wicker or something like the loop, or even a cellulose material like they make straw hats with. The wire is not that problematic since it is very thin to maintain lightweight. It is short and easily broken and doesn't present a high risk to wildlife. It should also oxidize fairly rapidly and just turn to iron oxide dust. I find fine winding wire like this discarded in junk piles in the brush and it just crumbles away, whereas thicker bailing and barbed wire persists for quite some time.The main criticism I have of these is the excessive packaging. Each lantern is packaged individually in an acetate bag. They have a paper wrap taped over the fuel square, I imagine to keep the wax from melting onto the lantern paper. And they include a bag of desicant. I can imagine that a lot of lanterns could be ruined by excess humidity, but there must be a better way to package them in bulk. Launching a fair number of these will produce a lot of trash just in the packaging, not to mention the lanterns themselves.It was very enjoyable to watch them launch with my wife and little ones. They fly so high so they look like stars, only brighter and very yellow. I can imagine launching many of them would be quite spectacular, but it would certainly take a lot of coordination and people to help in the effort. Even with the pre-heater, I could barely get a few in the sky at the same time before they were burning out. I'm just saying, don't imagine launching ten or twenty of these at the same time unless you have a lot of help that can work with fire (not little kids). Enjoy!
