Today is a double feature day here at Ecigclick with the introduction of the Indulgence Sweet Tooth line.
I’ve always had a liking for Unicig products from the Mutation X through to the Hera Tank and all those Tanks, RDA’s and RDTA’s in between.
Unicig are one of the leading electronic cigarette manufacturers in Shenzhen China, since 2008 they have been dedicated to bringing innovative products through their designs.
The Indulgence ST RDTA and 2ml Stock Tank
The Indulgence range of products have always shouted quality with great performance to me so let us find out what Unicig have in store for us this time. Will these Tanks be sweet or leave a sour taste in the mouth.

Design and Build Quality
Both tanks are made of 304 grade stainless steel and Pyrex.
They are topped off with Delrin drip-tip’s and like the rest of my experience with Unicig products, they are of excellent quality.
The designs for both Sweet Tooth tanks are very good and well thought out, totally in keeping with what I expected from UNICIG, all threads are smooth and work well.
The RDTA is a dual coil tank with velocity style block posts, while the 2ml tank holds a single stock coil head in a cup.
No machine oil residue was found in either tank.
A quick guide to changing the coils and filling the tanks
You do not have to empty either Tank before changing coils or cotton.
Sweet Tooth 2ml Tank
To change the stock coil:
- Press down the airflow/top cap (it’s a child lock feature)
- Remove the chimney
- Remove old coil and replace with a new one
- Fill the tank/cup half full with your e-liquid. Don’t go over half way or you will have a flood as the coil displaces the liquid when replaced an screwed into position
- Remember to pre wick the stock coil with a few drops of liquid through the top of the coil to wet the cotton.
Sweet Tooth RDTA
- Close off the bottom airflow
- Remove the top cap/ airflow ring
- Place your coils in the velocity style block posts, wick to your desire!
- The ST RDTA has a fill port on one side rather like the Limitless RDTA that you can open and close!
- I recommended you only use a needle nose bottle to fill the tank (don’t forget to prime the wicks and close of the liquid port)
- Replace the top cap/airflow ring.
How Do The Sweet Tooth Tank’s Perform?
The Sweet Tooth 2ml Stock Tank disassembles into 4 pieces:
- Cup or tank
- Stock Coil
- Chimney and top airflow
- Delrin Driptip
Cup/Tank
Made of 304 stainless steel and Pyrex with a silver plated copper 510 pin.
Take care of this part of the tank! If you break the glass you will be looking at buying a completely new tank as the Pyrex glass is not replaceable. Only fill the cup/tank to half full.
Stock Coils
The tank comes, pre installed with a 0.5 kanthal coil rated at 15 to 30w the spare coil is rated the same but is a stainless steel 0.5 coil.
Chimney and top airflow The chimney holds the stock coil by threads, the airflow is of a cylon style continuous spin action dual airflow (in other words it has no stop guide for the airflow), the top airflow has a child lock feature which you have to push down upon before you can remove the chimney to fill the tank or change your coil.
Delrin driptip tops the assembly off.
The Coil Adaptor comes as an added bonus that will allow you to use BF coils made by Joytech and Totally Wicked, the adaptor just screws into the BF coil and into the chimney section.
Using the BF coils will allow you to have maybe an extra ½ ml of liquid in the tank as these coils are a lot smaller than the supplied coils.
The Sweet Tooth RDTA disassembles into 6 parts.
- Fill port and build deck
- Base and bottom airflow
- Sleeve and airflow ring
- Pyrex glass tank
- Top cap and airflow adjustment
- Driptip
The Fill Port and build deck
Featuring a velocity style block build deck with wick holes to poke your cotton through to the tank.
The internal airflow is integrated into the block style posts as a centre post/chimney.
The air goes in through the adjustable bottom airflow on the base and strikes your coils from the bottom or centre depending how you have your coils seated.
The posts or blocks are of a four hole design, it’s extremely easy to install your coils.
Because of the design of the posts/blocks the peek insulator is situated inside of the centre post. The liquid fill port is closable
Base/bottom airflow/ Pyrex tank
The Stainless Steel, build deck screws onto the base so your coils are seated over the pyrex tank, the base has two bottom airflow slots that are a single stop action airflow, the Pyrex tank sits over the base on a couple of O rings.
Sleeve and airflow ring top cap
The Sleeve slides on over your coils and has a separate airflow single and dual adjustable airflow, the airflow is handled and adjusted by the internal ring attached to the top cap the top cap has notches cut into the Delrin to help with the ease of adjustment.
Delrin Driptip
Topping off the RDTA assembly is a wide bore chuff style 510 driptip. In the spares baggy you will find a 510 adaptor so if you wish you could use a 510 driptip on this RDTA.
Both Tanks were tested for continuity with a homemade e-liquid I like to call Cheeky Chimp; it’s a salted peanut and banana liquid.
The Sweet Tooth 2ml stock coil tank
At 25w and airflow wide open sitting on my eVic Primo the tank provides an excellent Mouth to Lung style vape full of flavour.
Knocking the wattage up to 30 then 35w with the airflow wide open I was able to get a restricted Straight to Lung draw.
The flavour was not quite as full on as the 25w MTL. The vapour production was good with both styles but truth be told not as good as the Hera tank.
The Sweet Tooth RDTA
This tank is all about airflow and clouds.
Sitting on my Noisy Cricket v2 with a dual pair of 0.4 coils, the dial turn to the fullest setting of 6 volts and airflow open to its fullest the amount of vapour was extraordinary and the flavour was good.
Turning the bottom airflow off and restricting the sleeve airflow to only one space open also turning the power down to 3½ to 4 volts I was able to get a passable MTL draw but I felt that the airflow was still too airy. However, the flavour was even better than that of the 2ml tank.

Pros
- The build quality of these tanks are excellent
- Great vapour production from the RDTA, good from the 2ml Stock tank
- The flavour from both was excellent
- The RDTA is very easy to coil being a velocity style block deck ideal for those new to coiling
- The 2ml tank is no fuss coil in and go tank
- A bonus with the 2ml tank is the coil adaptor
Cons
- No real big cons with either tank
- I will just mention the fill port of the RDTA you will need to wait for the coils to cool before opening the port or risk burning your fingers
Final Review Verdict
Well done Unicig these tanks are indeed Sweet! From design, manufacturing to the end user i.e. me!
I have already said I like Unicig products these two tanks for me go well beyond just like!
They are both designed for the novice user easy to use at all stages, I would happily recommend them both.
Would I buy the Indulgence Sweetooth tanks again if I lost or damaged either one? Oh yes!
The RDTA would be on my shopping list first as it’s a far better fit for me. But for travelling in the car the 2ml stock coil tank is also a winner in my book.
