Fake from Vapor Hub
My pictures from the tank they gave me:

Here you can see the rubber part(i think its call an insulator) sticking out under the build post and also at the back you can see the top cover with the engraving Avocado which on the V its half faded and grayish . The authentic one is not supposed to be even colored.
Here is the picture of the SS version engraving from RIP TRIPPERS review.

The engraving follows the color of the base which is either silver or black as shown below in the authentic black version i bought.

Here is the picture another forum member markypcs who was cheated as well just sent me a picture of his clone black version from Vapor Hub.

As you can see his engraving is grayish. Also in the picture above you can see the tank is with a clear glass. All the authentic ones come fitted with frosted glass and the clear glass tank is where the extra accessories are at.
The easiest give away is if you look at the first picture, you see the screw holding the fill hole hinge on the clone is gold and the original ones(SS or Black) comes with silver screws only as shown below:

Here is a picture showing the color of my authentic avocado black fill hinge screw.

Also in the picture above you can agak agak see the insulator and how good the workmanship is on the authentic one.
In the picture below you can see a stone chip in between two of the o rings due to poor workmanship of this clone.

Also can you spot a screw missing on the top post? The screw basically just fell off when i opened the tank brand new from the box and was sitting on the build deck.
Other giveaways of the clone:
- The biggest dead giveaway is the clone, you are able to pull the most upper part(the part that controls the air hole) out. I tried pull the top part out of my authentic one and from looking underneath, i can confidently say that the top and middle parts are joined together and there is no way to pull it out. In case you don't get what i mean, the picture below is an illustration of the part i was able to pull apart.

- Both tanks were clear instead of one being frosted.
- The ceramic block inside(if you decide to use single coil) is supposed to have 2 o-rings on both its legs but the clone came with only 1 o-ring on one leg for the block. The spare one also had only one o-ring.
- Very hard to pull out the liquid hole hinge cover.
- In between the liquid hole hinge and the fill hole, there is suppose to be a plastic cover which the clone does not have.
- The packaging part where on the front it writes Geek Vape, easy to build etc. That paper on the authentic one is really thin like an a4 paper. The original one was hard like a higher gsm paper.
I hope this helps you distinguish between the clone and original one.
