DH has been using his for about a week now and mine will arrive today. We're very impressed so far.
A couple of possible issues I noticed right off the bat were 1)if the batt covering got skinned there could be a problem and 2)juice leakage from the bottom of the cone onto the switch button.
Someone mentioned using a dab of nail polish on the battery covering (which I think would work), but just make sure to apply a couple of THIN coats instead of one thick coat...the fit is very tight and a glob of hardened enamel could cause issues with getting the batt back into the tube.
As for a juicy switch, so far we haven't had a problem with it, but we take care not to over-fill the atty (we drip), make sure we give it a little wipe down now and then (around the atty connection, the cone threads, and inside of the cone), and, at night, remove the atty from the unit and give everything a good wipe-down.
If the manufacturer would add a thin "gasket" (maybe at the very top of the threads on the batt tube), I think that would take care of it nicely. I think I'm going to get DH to make one out of something (what exactly is unknown at the moment) this weekend just to be on the safe side.
Now if the postman would run a little early today...
