I seen they have 3 ohms. Is there a difference in throat hit with 1.5 vs 2.0 or 3.0? I don't like a harsh, huge throat hit? Oh, do u need a drip shield? I imagine as long as your safe your OK, then again s**t happens so ya never know.. Ty again
I've never tried a 3ohm atty to be honest. But like I said, both of your devices are variable, so you can probably get any of the resistances you mentioned and adjust them to find a vape you like. Higher resistances will usually give you a tiny bit more battery life but when you fire them, they will take a tiny bit longer to heat up. Really, the difference will be small, almost to the point of being insignificant, so pick a resistance to start with and go from there.
As for a drip shield, if you go down the 510
sealed atomizer route, no, you won't need anything else. A drip shield is a specific device to stop over-drips going down into the battery. This is only an issue if you get an
unsealed atomizer.
Unsealed atomizers are really good for other applications (like liquid bottom feeders like a REO or a VMOD) but for simple dripping, I'd always recommend a sealed atomizer. As I mentioned previously, if you have a sealed atomizer and put a few drops of juice in too many, you will get poor vapor and flavor and get a gurgle. Just flip the atomizer upside down into a tissue and let the over drips come out, flip it back around and vape away.
In this same scenario with an unsealed atomizer, you will literally see the over drips come out of the airhole on the base of the atomizer and leak onto your battery.
A particular favorite atomizer of mine is the Kidney Puncher long barrel
atomizer It's inexpensive and I would put the performance of it against some of the higher-end 510's out there. (Their shipping might be a little higher than you are used to)
I linked to their main atomizer page, you can see both sealed and unsealed on this page.
Best advice I can give is just buy one, give it a try. You'll be in less than $10 and it really will open up another vaping experience for you. Those links Susan posted are a great place to start too.
