Got 10 of the GotVapes Vortex's and I love them. 2 of them leaked out of the box, I fixed the 1 and gave away the other one.
They are PURE flavor and great vapor. I haven't used the CE2's, so can't compare.
The main drawback is that the end cap will easily pop off in your pocket, and you can dump your juice in your pocket.
I've cut a hole in a condom and put that over the rubber endcap and that holds them tight.
I think you can also put some teflon thread tape or clear tape on them and that makes them stay too.
I used these on 808 batts, and they're a cooler vapor than a carto, but the TH is good, so with the increase in flavor and the fact that they last all day it's easier to accept the cooler vape.
The Heaven's Gifts one's do appear to be the same, minus the ALF.
