No pics yet but my UCO Mini showed up today. Very nice! Larger than the Micro by a bit and not collapsible, but it's got a much larger glass globe, so it seems like it puts out more light. It's simpler than the Micro but as it lacks that wobbly/flimsy slide opening system it feels more robust.

I burned an 8 hour paraffin in it and it worked wonderfully! I'm not sure if it's worth hacking/messing with the Micro for this purpose. The Micro works well with candles, while the Mini seems almost made for fuel cells.

I'll undoubtedly do some more tinkering and get some pics but I'm liking them both so far.
