I recently started that quest! I love my Triton VV (will never go back to regular), but I did have one gripe...its size. It's fine for home, but at work (we can vape) it wants to fall out of my shirt pocket. So I decided to order a Joyetech 650 Twist, along with a Kanger Protank 2 mini.
Here is my first experience: I open up my eagerly awaited vapemail and marvel at the beauty. I charge up the batt and decide to clean the tank before first use. I take it apart, and while holding the glass part under running water it slipped out of my hand, landed in the sink, and shattered! Worst. Christmas. Ever.
So now I sit here puffing on my Triton while I wait for a replacement tank. So far, Halo-1, Other Guys-big fat ZERO!
Ok so I admit the tank breaking was user error. But still, almost 3 months now and this clumsy newbie has had zero problems with the Triton.
