I just received my Tox from Litecigusa yesterday. I just watched your review and completely agree with everything you said. Inconsistent hits, subpar build quality, finicky switch, etc. When it works, it works quite nicely.
When I received mine yesterday, the battery charger, which is complete garbage by the way (IMO), was broken. The pieces of plastic were separated from each other, and the metal blade that holds the battery in place fell out when I took it out of the package. I immediately emailed Litecig, and they have a new charger coming out to me now.
I noticed the Unavailable message on their website this morning, so I sent an email, they replied "just a couple of units were having issues with voltage output".
Seems like it may be more than just a couple of units.
