Well, in my case I've been
vaping all these liquids for over a week so I know they are fine. What's new is these Ego Mega attys I received today, 4 of them.
I opened the 1st one, blew out the primer, loaded it up with menthol (50/50 pg/vg) and soon after I was in vaping heaven. I spend like 8 hours with that one then I got tired of the menthol and decided to load 2 more attys with strawberry and RY4.
The strawberry was 100% vg, thicker juice and it seems it was a lot slower @ wickage. I also forgot to blow the primer out so it took me some time to get that atty going. Then the RY4 was 100% PG, it gave me another primer hit as I forgot to blow the primer again. It was so awful I tried to drip a little... but I flooded the atty... blew it out for a long time, then fired it up. It's not yet perfect but is getting there.
Then I kept alternating between these 3 attys, menthol, strawberry and RY4... for like an hour, and my mouth started hurting and felt all tired. I'm not sure if it was the extended chain vaping or the atty blowing.
I put the PV down and let it rest. I wanna vape, but I'll wait. I'm sniffing the cap of the RY4 atm

... lol, the things we addicts do.
