I stopped believing the B.S. that one has to "break in" an attie a long time ago. After giving the atty a good flooding, it should work perfectly right out of the box. Of course the peformance begins to degrade almost immediately.
Well for me, a brand new atty doesn't give the full taste of my eliquid, usually it takes just a few hours, like 4. It's especially bad the first 30 minutes, after this it gets much better every draw.
I've had atties that needed a little breaking in before, but I've never had a brand new one that doesn't deliver taste like the one you describe. It might be a bad atty or one where the resistance is much higher than it's supposed to be. If you have a multimeter you could check the resistance to see if that might be the problem. You might also try drowning it in your e-liquid for a few hours to get it to absorb the flavor better. If you have one of those cartomizer condoms you could fill it up with liquid and set your atty in it for a while.
I tested it with a multimeter, reads 2.1 like it should be. LR atty. I also put it in my liquid for around 5 hours in a carto condom and it still tasted bad. There's a white filament of something sticking out from the bridge and is now glued to the side of the atty on the metal. I also checked my 25 other brand new atty and 3 of them are also like that. It's like a very small white rope that's getting burn, maybe I'm vaping this and this would explain the bad taste. First time I'm seeing this.
I never really had to break in my attys, other than blowing out the preservative juice that comes in them. And sometimes you just get a bad atty. I would just toss it if it's been 24 hours and its still not perfroming.
These atty from greenhouseone doesn't come with any preservative juice, doesn't look like it's making any difference, they're very good and cheap. I guess I had a bad one tho, my first one out of 10 ! It's in the trash now.
Thanks all for your input!
