Hello,
I have been a long time lurker. After waiting for my July 2015 preorder, I just decided to get it from Vapefiend, and after a week long wait, it finally arrived today!
First Impression: Like others have stated before, the build quality is amazing. After inspection the exterior, I pulled some hot air through the device. Not to my surprise, the mouthpiece gets kinda hot... However, it's very manageable. To compare the experience, it's like getting into a hot bath. Soon as you put your foot in the tub, it's very hot, but after a while, you get used to the temperature.
Charging: After visiting this forum religiously, waiting for my Hopper, I have also noticed a correlation between the stock charger and failure rate. So, I have ordered an external charger (Xstar MC1 Plus). But I, an impatient man, tried out the stock charger. Interestingly, if I put my ear close to the hopper while it's charging, I can hear some kind of weird static sound, like the kind you hear on a poorly recorded song. I'm not remotely knowledgeable on electricity to find out the cause, so if fellow Hopperians can try it to make sure that it's not only my device that's doing this, I would be grateful.
Overall, I feel like this would be my final and ultimate vaporizer for years on end.
