Very few delivery devices come close to an optimal functioning RBA in my experience, and I don't use ULR (sub 1 ohm) coils. I build only 2 ohm coils and use them on regulated electronic APV's. When the entire device is functioning optimally the vape is extremely smooth with great flavor and vapor production. I sometimes am not aware of just how much vapor that I'm taking in that I'm shocked at the amount when I exhale, it's that smooth.
I had never been to a hooka bar before Father's Day, when my daughter, her boyfriend, and my son treated me to one. The experience surprised me in the similarities of the two.
The problem arises in that minute things can occur to the coil to change the resistance and the entire vaping experience, and if dealing with ULR coils this can lead to dangerous situations. I've been an "advanced vapor" for almost a year, and gained quite a specialty with cartotanks. I only took up RBA's in the last couple of months, because I had read up on them and respected their complexity. I'm just now gaining some confidence in their use, but knowing what I know about them I still treat them with respect in regards to their safety issues. RBA's push the batteries that we use to their limits, and they were not specifically designed to do what we sometimes ask of them. If you don't know what you are doing, you are putting yourself and others in potential danger.
The people who use ULR coils do so in mechanical mods, which have few if any safety features built in them. In fact, the reason they use mech mods is because they can bypass the safety features that regulated electrical mods have. Now, when you think about that, how wise is that? The couple of safety feature that mech mods have, a hot spring and vent holes, are only useful AFTER a battery decides to hard short and go into thermal runaway. Severe burns or fire damage to physical property can ensue. Has no one seen the pictures of the Smoktech Groove's that have hard-shorted and have been recalled?
PBusardo recently did a rant about users of ULR RBA vaping and voiced his concern, and quote, "Sometimes just because you can, doesn't mean you should." Anyone who uses ULR, or is considering it, should listen. It's at the 3:00 - 6:00 minute mark of this video: A PBusardo Rant & Review - The NZonic V3 - YouTube
