Ystar Vitamin RDTA review

The Ystar Vitamin review, a genesis style RDTA with some premium features.


Ystar Vitamin Tank Intro

The Ystar Vitamin tank is genisis-style RDTA in the same vein as the Geekvape Avocado and the Limitless RDTA with a bottom tank and top adjustable airflow. But that’s where the similarities end as the Vitamin offers some other compelling features.

From the outside, the most striking characteristic of the Vitamin is the PEI (ultem) top cap, which is often a desirable third-party option but standard with the Vitamin.

Remove the ultem cap and it gets even more interesting when you see the postless deck. With no posts and huge wire holes, the deck is open to larger builds using your favorite 12-strand fused alien flattened rhomboid staple wrapped Van Halen tiger wire (just want to see if you’re still reading).

The Vitamin tank is 24mm in diameter with a capacity of 3ml (as measured with a syringe), made from 304 stainless steel. and available in three finishes: Black, gold, and brushed stainless steel.

Retail price is $59.99.

Notable Remarks

Firsts things first


There were a couple of firsts for me in using the Vitamin RTDA. I had never built a postless deck, nor had the opportunity to vape with an ultem cap.

First, the deck. Using single wire coils, like 24 gage Kanthal, is doable on the postless Vitamin deck, but it is not optimal and can be tricky when trying to capture the coil leads behind the deck screws. I got it to work but this deck was obviously designed for heavier wire and I was able to easily capture the leads of clapton wire coils. Now that’s more like it.

Something else to note regarding the deck is the lack of a side fill port. There is a small opening in the top of the deck that will accept a 1.5mm blunt tip syringe and almost fits a pointed unicorn bottle tip, but that is a bit of a hassle to use every time you want to fill, and with fused claptons, this build is going to drink some juice. The only other option is to fill using one of the wick holes – also not optimal.

Second, the ultem cap is fantastic, it looks cool and vapes cool and has a perforated anti-spit shield. Not much more to say.

One final note: This is the very first rebuildable atomizer I have used that did not come with a tool to tighten the deck screws. The tiny slotted grubs had me digging through my tool box looking for a jeweler’s screwdriver that was small enough to fit into the deck side openings to turn the screws, and every little blue screwdriver I have (over 20?) is a phillips head.



So, I scrapped the nichrome coils, rolled up a couple of 3mm fused claptons and my build came in at 0.54Ω. With no side fill port, I filled the tank first then wicked the coils with strips of Japanese organic cotton, trimmed and poked the wick ends into the tank. I primed the coils, replaced the ultem cap and vaped at 45W.

Feels like I am floating on a cloud of pure vanilla custard, warm and thick. Doing a bit of chain vaping, the ultem cap is warm but not hot. I hear a few pops but no spitback as the perforated anti-spit cap is does its job perfectly.

I alway try to push the wattage beyond my comfort zone, which in this review was 80 watts. I know, not much, but for me the vape was hot – yet the cap merely got warm.

Back to 45 watts and I’m doin’ fine…


  • Good vapor
  • Good flavor
  • Ultem cap coolness
  • Spitback protection
  • Easy to wick
  • Generous airflow
  • 510 pin safe for direct-to-battery use


  • No side fill port
  • No single coil option
  • No screwdriver included


Honestly, I’ve always been intrigued by the postless deck but I have never actually tried one until now, so I may not be the best person to judge this one. The postless Vitamin is a bit challenging to build when compared to the more common Velocity style deck – but the Vitamin definitely excels when using heavier wire like clapton coils, so I’ll chalk it up to my inexperience with the postless deck, rather than blame the Vitamin deck.

I am disappointed however by the lack of a side fill port, as found on the Limitless RDTA, and also believe that Ystar is missing a segment of the market by not allowing for a single coil option with a plug. And I never thought I would say this, but… I sure wish they would’ve had given me a tiny blue screwdriver.

All of that aside, there are some positives. The Vitamin vaped quite well and I like the look of the translucent ultem cap, which is often a premium upgrade (some aftermarket caps as high as 50 bucks). Functionally, ultem gives a cooler vape and the Vitamin cap includes spitback protection. The postless desk gives you a lot of room and accepts large diameter wire for your exotic builds, and for you direct-to-battery fans, there’s enough 510 pin protruding to make even your grandma comfortable.

The Vitamin may have some minor faults but none are an endgame for me. I’m not sure I would get one only because I’m spoiled and don’t want to fuss with refilling it or deal with a postless deck, but the deck may be a plus for those looking for a wide open canvas to build their masterpiece.

    I like the Cyrillic alphabet, It’s my first anyway 🙂 Витамин haha, unique name. I like it. thumbs up

      It’s definitely different and does look kinda cool. Wonder if there was another reason they chose Russian. Though I wondered at “Vitamin” as well…

      • I don’t know if its Russian or not. I’m Bulgarian and “Витамин” is definitely a Bulgarian word and means exactly the same (VItamin).

        P.S. If its russian must be ” Витами́ны ” ..

          Well, thank you, my Bulgarian friend. I’m a bit smarter for that. 🙂

    Thanks for the review. The Vitamin looks awesome, but the lack of a side fill port kinda kills it for me.

    • Gary Joseph

      I agree on the fill port but after writing this review I saw a video (unofficial) of a Vitamin which did have a fill port, very much like a Limitless RDTA. Mine didn’t and there was no indication that the sample was not a production item, so I wrote it that way.

      We probably will need to do some further research and update the review as needed.

      Thanks for the comment.
