Just got my Aspire ET's and Mini Nova's on Monday. Both been working great. Well this morning I noticed that I was getting a little gurgling from my ET. So I took it off and had a slight puddle of juice on the battery. Chalked it up as a fluke and put it back on. A little while later gurgling again. Same thing. juice on the battery. So I put it back on and immediately took it off and there was a puddle. Did this three times with the same results. So it looks like the leak is getting progressively worse. Figured I would break out the Mini Nova and see if it had any issues. Well now it has developed a leak as well. Put it on and take it right back off. Immediate puddle. Looks like this may be an issue with the heads.
