I don't have an original Zeus X atty but I have 2 of the original Zeus dual RTA atty's and I think this is an improvement. The inner chimney in the Zeus X is awesome. It may be aluminium in this copy but I have had zero spit back of hot juice. It seems to make the whole draw smoother. The posts felt like aluminium too and will strip out threads. Actually I think 1 screw started to strip thread on the first build. If you can't get decent tension on the coil wire it is no good. These aluminum pieces need to be made in stainless steel and offered to people that have already bought this item at a very low price because even at $8-$9US it has to be able to be rebuildable a good number of times.

Always good to have some spare glass around hey. It is glass. It is in the shape of a tube. And it is very glassy.

A cool 510 mouth piece with adjustable glass tip that slides up and down a bit. Works quite well on the pen style vape mods. Glass breaks easily.

Another attempt to try to get that vapour a little bit cooler before it gets to your lips. 510 for vape pen.

Heat sink for pen device. Small 510 mouth piece adapter. Attempts to cool vapour a little bit before reaching the lips but none can do that in that small space and time. Looks pretty cool though it is another place to fall apart.
