I know what you mean, I cant even pour the wax without spilling a bit when its that watery, that is why I'm not convinced when they say that its normal.
Yup I keep mine indoors 100% of the time since I had it but it looks different and flows really like water to the point where I really can't control the flow when poured in an foam pad. I really hope...
I had the same problem and gave up on it, even after charging and discharging several times. I wish they would come out with Li-Ion or Li-Polymer battery version.
