Gemz Prime Mover RTA review by Mjag

Hello once again and thank you for taking the time to view my review of the Gemz Prime Mover RTA that was sent to me by my friends at
  • 3ml capacity (both in tall and short mode)
  • 24mm diameter 42mm high in short mode, 53mm in tall mode
  • 304 SS
  • Colors: Black/Gold/Silver/Rainbow
Comes with:
  • Prime Mover RTA
  • Extra Drip Tip
  • Extra Glass Tube
  • 2 coils
  • Owner’s Manual
  • Spare o’rings
  • Allen wrench
  • Micro fiber cloth

So what’s with this tank?
Right off the bat I was not crazy about the steampunk style engraving on the top of the tank. Looking at pics on the net it looks like the Black I got was the least flattering, the Gold, Rainbow and Silver look better to me but that is all subjective.
Check out how sexy the other colors look:
You get 2 drip tips which are proprietary and screw in. The longer of the 2 makes the tank taller and also allows you to fill up the tank without unscrewing the drip tip. You just press down on the spring loaded top and twist to lock down. Fill up then twist again so the top springs back up to the drip tip. The odd thing is it makes it taller but doesn’t increase the 3ml capacity. I tried the taller drip tip but mainly just used the smaller one and kept the tank more compact.

Short mode
The drip tips are proprietary but you can stack 810 drip tips on them. There is an o’ring on the inside so friction fit Kennedy and Goon style 810 drip tips fit just fine as well as 810’s with o’rings such as those for Smok TFV8/12.
Friction fit 810
The build deck looks like a typical GTA style except for the 2 airflow diverters on each airhole. I can see what this is doing, diverting the air so it passes under the coils.
Huge wicking slots, I would suggest 3mm inner diameter coils so you have enough wicking to fill these monsters. It wicks like a champ though.
Your coils will be mounted at the same time so you will need to clip the leads prior to installing. I generally like installing coils 1 at a time but this was easy enough and the grub screws are of great quality so kudos to them for that.
Either clip them prior to installing
Or if using a coil jig it works fine to just clip them even with the barrel of the jig
How is it to build?
I actually found it rather easy but also found that coil positioning will affect your airflow. If you like a more restricted draw and a dry vape positioning your coils low will yield the results your after. If you like a more airy vape then position the top of your coils right to the top of the posts. The higher coil position can be a little spitty with some builds though, not hot lava in your mouth but more of a wet vape.
Low build
High build, my preferred coil height and the wicking cut about even with the deck produced great results
I ran 6 builds through this tank and found that the higher coil positioning was my favorite but none of them are bad. I am currently vaping it with the low coil position and a simple clapton build with good results.
One thing I noticed though is with some coil positions you can develop a whistle with the airflow wide open. If I close it down just a little the whistle goes away.
This is a small chamber so I didn’t even attempt to put a big Alien build in there. The largest I put was a quad core parallel clapton and with high coil positioning I got excellent results.
Flavor and clouds
While not the best flavor I have gotten from a tank it is pretty good with the right build. I preferred a high coil position, get the coils closest to the top with shorting. With a low coil position the vape was noticeable dryer and cooler but I was still able to get decent flavor.
Definitely not a clouds bro tank but the size should tell you that. I get decent clouds though, think Soloman or other small GTA styled tanks.
Overall the flavor and clouds are a step down from the best out there. I am sure this will satisfy many people though and for the last 2 weeks I have been happy using this tank except for one thing.
What’s that one thing?
Seeping issues around the airflow control ring. When I first encountered this is when I had the Gemz RTA with me the whole day and filled it up about 6 or 7 times. When I got home I went to put it on another mod when I saw this:
Then looking on the bottom of the tank the condensation was real bad.
At first I thought maybe it was leaking but no, this was just condensation that had built up and the seam around the airflow control is loose enough to allow the condensation to build up. Nothing got into my 510 but over time the condensation builds up between the tank and mod. I started using a plastic mod protector and that keep the condensation off my mod.


Now there are some definite cons with this tank but after 2 weeks with it I have the urge to order the Gold version. That urge wouldn’t be there if I didn’t actually like the tank. Sure I wish I could use my own drip tips without having to stack them on top of there proprietary drip tip. That is not enough of a con to stop my want of the Gold one though. Sure the condensation build up sucks but with a mod guard under it is not much of a problem.
I can say that I got enough enjoyment out of this tank that I am really tempted to buy another one. The black I received doesn’t float my boat in the looks dept but the gold one sure does. That is my general measuring stick, would I buy this product? With the Gemz Prime Mover RTA the answer is yes if it is the Gold, no if it is the Black.
I want to thank for sending me the Gemz Prime Mover RTA to review, it wasn’t even on my radar, it is now though.
