First off, I am also a noob at all this pretty much. I have a good line on some medical grade concentrates now but I was always vaping flowers primarily until July. Since then I have been sticking with primarily concentrates. I have been using the Yocan Evolve Plus with the QDC and Donut Coil atomizers and while they work decent and I prefer the donut over the QDC, I still feel there has to be something better. Something that does not allow reclaim to sit under the heater like donut coils do and does not get caked up like coils do and does not allow reclaim and splatter to stick to the walls. This is where the Terra 2 coils interest me. I am a high tolerance type of person so the Source orb XL interested me in that you can load a gram in there. I feel a quarter to half gram would be perfect for a quick session or two but with the Yocan Evolve Plus this takes 4 or more atomizers to truly get efficient results from that much concentrate. It either goes under the heating coil or splatters against the walls and sticks around... On top of all that...I know nothing about mod boxes and have been very hesitant to get one because there are so many and I don't want to learn about them to know what I need to make sure I buy the one that can do everything for what I might ever use it for. I may use this for the Source Nail one day but I don't know. I also like replaceable batteries if your Mod's have this option. Lastly, the price point was a big point for me. I don't want to spend $200 right now, but I feel like the $120 price point was right up my alley!
