I was impressed with the build quality and performance of the Eternity, the vape was cooler than I usually prefer but I did REALLY like the draw, and the flavor and vapor production were quite good.
The DESIGN is absolute garbage though. The insulated post that you push the little coil blocks onto is weak, and WILL break eventually depending on how lucky you get. It doesn't snap or anything (although I guess that's possible) but it's too weak to put up with the large amount of force needed to seat those little blocks.
3 coils is what I was able to go through before the post got wobbly and started shorting out. I could check my atty rez on my mod and it would change from 2.5, to 2.2, 2.1. 1.8. 1.5 and keep going down as the the post moved around, shorting out the device.
This tiny, single flaw is a huge deal breaker for me. This 30 atty is completely useless now. There is no way to "get into" the area underneath the coil to fix the wobbly post.
On one of those China sites I've seen an Eternity knockoff that uses small screws INSIDE of the post, with a horizontal hole lower down. You don't need to remove the screws, just loosen then a bit, insert your wire, and tighten it down. Much easier setup than the Vision, and you don't need to put ridiculous amounts of force on that tiny little pin.
But when copying the ET they forgot to include that little air tube that sticks up right underneath the coil. I'd imagine this woud cause severe leaking, as that tube is where the airflow comes from, being raised up it's much more difficult for
juice to leak through it, but if it's flush with the bottom like on the knock-off juice could easily leak out.
So the china copycats got one thing right, the posts for the coil, but they screwed up somewhere else.
Vision got it right on the air tube, but screwed up big time on the posts.
If these posts were fixed I'd buy another ET even after swearing off Vision products (every single one I've had, Vivi Nova, other clearo, twist, ET) were all complete trash and either broke or failed to perform. But better pins would convince me to get another ET.
