I received my Cuboid Mini kit today and figured I'd leave my first impressions here.
I'm even more pleased with the design than I thought I would be. It feels great in the hand and the build quality is fantastic. It's even smaller than I expected and fits snuggly in my front pocket next to my phone. As we've come to expect, Joyetech's board works like a charm. Unfortunately, it's not all peaches.
First; holy spitback! Even at 170 Celsius, which I'd consider barely acceptable for direct-to-lung vaping, I get spitback frequently. Anything above 175 Celsius is unvapeable. I've since learned that this has been a recurring issue with the Cubis coils and it seems like Joyetech has not eliminated this problem with their new Notch coil. I hope I have a better experience with different coils/juice, or this atomizer will see a very early retirement.
Second; the Atomizer gets very hot. This is something I would've been able to live with if it didn't liquify the glue they used for the plastic cover overlaying the juice window. This leaves a clearly visible fog in front of the juice window and made it incredibly easy to peal off (it looked ridiculous). I was able to stick it back on this time, but I'm afraid it's only a matter of time before I lose it for good.
