I've had a problem with a burning taste with every one of my juices for the past week and a half. No matter what voltage I was using (3.7 up to 5) it all tasted burnt ecept for maybe 1 out of 10 drags. I used attys from several very reputable suppliers, and they all tasted the same after a few hours of use. Kind of like a burnt taste, but not as extreme as an actual burnt up atty. Not knowing what else to do I ordered a few genuine joye attys and a few from Volcano(the Magma 510) since I've always been lucky with both of these. What do you know, all the juices taste fine, no burning taste at all; at any voltage. I disected one of each of the problem attys and it seems the mesh that covers the bridge(and also wraps under the coil pot) is all blue like it was exposed to extreme heat, and it also crumbled apart when I touched it with the tweezers. Has anyone else received any of these funky ones lately? And yes, each of the troubled ones are regular resistance (2.5 ohm) attys.
