I have been using an original Luci for four or five years now.  When I bought mine it was close to $30 and they sent another to a third world county for use.  It has held up very well, but last year I developed on hole in it.  Put a little Gear Aid sealer on it and still going go so far.  When in the CCS lean, I hang it from the quad loop.  Luci got a big workout last year in May during the snow/sleet/rain day playing cribbage.  When I'm in the warbonnet blackbird, I hang it from ridge line on the tarp.  I have never had any issues with it running out of juice.  When I get to camp, blow it up and set it in the sun and it's ready to go.
