Let's just say I don't dab or use thc. I use my orbit for en entirely different substance that absolutely requires a coil-less atomizer. I have tried many. Many systems, swordfish, puffco ect. The orbit is so darn reliable and the terp pearls even work with the substance I vape! It's in a class of its own. It was this or slend hundreds of dollars on a divinetribe crucible style atomizer. I'm sure the divinealright it's much better but for The huge difference in price, The orbit searched me very well. I wish they had better quality control on the coil head themselves, I have bought threextra coils and 2 of them have been so off. Centhat the vortex generating Piece cannot do its job. That aside, these coils will last you a very long time just make sure to use a bit of 99% isopropyl alcohol and squirt it into The Crucible and very lightly scrape the quartz with a pik and also occasionally heat up the alcohol while scraping gently and that will sufficiently clean the coil to make it look brand new again. My first one lasted me well over 6 months of multiple uses every single day and these next two are basically brand new. Make sure you do not submerge the entire coil in isopropyl alcohol and just put it into The Crucible instead otherwise the alcohol will eat up the special isolating covers on the wires underneath the coil giving you a useless coil. I was never a fan of the orbit battery, so I use an eleaf istick pico 2 as the battery utilizing the orbit atomizer and I couldn't be happier with the setup. Fires amazing and rapes my product even better, with interchangeable 18650 batteries I literally never have down time to charge since I have multiple High drain 18650s on hand.
