I got my kGO on Monday - I love it! It vaporizes the liquid much more efficiently than the Mistic I've been using for a couple months. In fact, it's so efficient that for the first few hours, I actually felt dizzy from the nicotine in the same juices I'd been vaping in my old setup. I think I spoiled myself, though - I bought the kGO along with a couple e-turbo tank cartos, and now when I use the cartos that came with the kGO, or even the Boge LR 2.0 cartos that I bought at the same time, they just seem weak (and loud). I definitely recommend you try the e-turbos! Vaping with the Boge makes a sound like you're slaying a dragon.
