Smok Novo Series is the best mods I've ever used. This particular mod has adjustable airflow, a USB 'C' type charger which I like better than the micro USB, and it has longer battery life than the Novo 2. I'm reading the other reviews and I noticed y'all are mentioning that the Novo 2X pods are very hard to take the tip off. This is definitely true, I also had to use pliers, bit the really good news is that you can use the regular Novo 2 pods on the Novo 2X mod. The Novo 2 pods are side-loading; you just have to take off the rubber stopper on the side. Overall this is my favorite mod because it's got an airflow valve on the side, it charges with a USB C charger and it has longer battery life than the smaller Novo 2. Would definitely recommend buying the Novo 2 pods for this mod instead of the Novo 2Z pods. They're definitely reverse compatible.
