Just to add some more info in case anyone wants to know for sure what version is at what vendor:
I have the "Phoenix V4" from Hoosier, the stainless one, I think it was around $7 It is fully made of stainless, the drip tip, cover, and base. The outer post spins a bit sometimes because the post isn't seated well in the base. I'm not sure how it's seated, whether threaded or just press fit, but I find if I push down hard on the post (as in putting it in a small vise to squeeze it gently but firmly) it will stay put for awhile. It's not until repeated recoiling that it loosens back up again. It was actually an advantage at one point, when I had a hybrid wick in mine that was a bit too big, and I rotated the post to move the coil over a bit relative to the deck, if that makes
sense.
It has allen screws not thumb posts or phillips head screws. The posts are some sort of plated metal I believe, not sure if brass or what else it is, but it's some sort of chrome plating or something on there.
The O-rings and top cap fit very tightly, I can easily screw and unscrew the thing from PV without the top cap twisting. The O-rings are black.
I also have the "Squid" in Stainless Steel from
madvapes, I think they are selling this for around $10 or so. Might be called the mini
rda some places I think too. This one looks pretty much identical to the "Phoenix V4" (as well as the real ERA) on the outside, SS cover, same drip tip as far as I can tell. But there are a few differences on the inside.
The posts do not spin at all, and there are thumbscrews instead of allen screws. The posts are some sort of brass colored plated material, maybe just polished brass, whatever it is, not the chrome plating like the Phoenix. The O-rings and top cap are a bit looser, they spin around more than on the Phoenix, and it's a bit difficult to remove or screw onto a PV without spinning the top cap. Air hole seems to be possibly a bit smaller, maybe my imagination as my Phoenix has already been drilled out and I can't compare them side by side.
Where as the Phoenix is full stainless, the drip tip, cap, and base, the "Squid" has a SS drip tip and cover, but the base is some sort of chrome plated brass, not stainless steel.
If anyone has some old (well, unused) vision clearos with removable bases, there is an O-ring that seals the base against the clearo's tube, it's a clear silicone type o-ring. These o-rings fit great on both the Phoenix V4 and the "Squid" in SS. These make the top cap fit very tight, to the point where the only way to adjust the air hole is to completely remove the top cap and reposition it. Just how I like it.
Anyway, they are both pretty near identical, although the Phoenix being full SS, while the Squid having a chromed brass base does seem to be the biggest issue to me. The thumb screws from the squid DO fit the phoenix V4, so if you had both you could swap the thumbscrews to the SS base.
They both vape exactly the same as far as I can tell, so any differences would merely be preferences on various materials and parts.
