Unfortunately, I have a different opinion from above. The lavetube, is basically, sub par to the knock offs. It doesnt offer battery usage and TBH I have not seen it do anything any other mod can do. The "clicker" sticks on 2 of 3 of my lavatubes. Not to mention volcano has failed to offer the LT2.0 in the last 3 months. If it were me, I would go for a vector from vaporbeast, I use it more than my provari.
