So I got my new dual wire 1.5ohm xl carto's from avid vapor, and also got two 1.5 ohm 510's, and a 1.8 ohm 510 as well. And I have a couple of questions. Do his 510's come with primer in them? I forgot to check, and when I was vaping the first one it tasted burnt or something, it really tasted nasty. It wasn't dry, if anything it was flooded, I could see the juice in the atty. After I tried it I tried to blow everything out of it, and then prime it and blow that out, then I put four drops on the bridge put it back on my grand squonked it and at first hit was GREAT then the following hits had that burnt taste again. I just can't figure it out. I also used my multimeter on everything, and all of them were way off. Are multimeters off normally. I have no experience using them, but the 1.5 carto was 2.0, the 1.5 cisco was 1.8, and the 1.8 was 2.0' so I was just wondering if that was normal, or if my $12 multimeter was not that accurate. It's an innova 3300, if that makes sence to anyone. Thanks for helping me out!
