This review is taking a closer look at the UD Anzu RDA. Before the review, let’s give you a little background on the company itself.

Youde Technology Co. Ltd is an electronic cigarette manufacturer based in Zhuhai City, South China. Many vapers will be more familiar with them known as UD. And most vapers will also know, UD have a massive catalogue of vaping products to their name.ud anzu rda

Everything ranging from CE4 clearomizers, Genesis style atomisers, RDA’s, RTA’s, coiling & wicking accessories, Mods, the list is endless.

What Can We Expect From the Anzu RDA by Youde?

Over the last 2-3 years they have focused predominantly on their Rebuildable Tank Atomizers, following their success with the original Goblin V1 RTA. However, UD have now jumped back into the RDA arena with their latest product, the Anzu RDA which features the ever popular 2 post velocity style deck and massive adjustable bottom & side airflow.

They say first impressions are generally correct and to be totally honest I wasn’t overly impressed with the Anzu when I first unboxed it. However, they also say never judge a book by its cover.

Build Quality & Design

Aesthetically, the Anzu is not the most impressive looking atomizer on the market, although it is very streamlined and the quality & finish to the device is of a very good standard.UD Anzu RDA review

The Anzu RDA can be broken down into its individual parts and reassembled with absolutely no issues and all parts fitted clean and flush. Overall the Anzu feels very sturdy & robust.ud youde anzu rda parts

The deck of the Anzu uses the highly popular dual post Velocity style design with 2.5mm post holes which provide great diversity when it comes to build styles.

Deck posts are fitted with flat-head grub screws which is a great change from the very popular Hex style, which personally I feel tend to strip far too easily.ud anzu juice well

On the base of the build deck we have two large (3.0 x 6.5mm) air holes each with a raised lip to retain E-liquid in the deck and also prevent leaking into the air flow channels. The juice well is reasonably deep with plenty of room for your cotton sit.ud anzu rda on mod

The Anzu consists of three main components; the dual post build deck, the bottom airflow section and an upper section which incorporates an airflow control ring.

You have a choice of drip tips to use with the atomizer, either the pre-installed stainless steel tip or alternatively the wide bore Delrin drip tip. Of course, you can always use your own 510 drip tips by using the included adapter.


The Anzu has an abundance of airflow! At the bottom of the outer sleeve, which UD refer to as the Stainless Steel Tank section, there are two sets of four large air holes which you can adjust to suit your desired vaping style by rotation the sleeve.ud anzu airflow

UD have also provided additional airflow at the top of the device with two sets of ten small air holes which can be fully adjusted by rotating the air flow control ring.

There is a slight problem with this top and bottom airflow arrangement, if you intend to only use the side airflow and close the bottom airflow down completely, the side airflow will not be directed at your coils.

Personally, this wasn’t an issue as I just preferred having the bottom airflow wide open and the side completely closed off as this seemed to provide a more flavoursome vape will still producing some respectable clouds.

Building on the deck of the Anzu is extremely easy thanks to the large space around the deck. Having flathead screws in the posts just seemed to make everything so much easier.

I tested a number of builds on the deck with no issue at all, finally settling with a dual two Framed Staple Coil setup with a final resistance of 0.2ohm. For the wicking, I use a generous amount of Cotton Candy.

How Did The ‘Anzu’ Perform?

My test e-liquid, as always, was Beard Vape No 5, which I have vaped for a long time and know exactly how it should taste & perform.

The first thing you notice when vaping the Anzu is how airy it is as there’s virtually no resistance!ud anzu rda coil

Performance wise, I was incredibly surprised, the Anzu RDA provides extremely good flavour. As mentioned, I found it performed best with the bottom airflow wide open and the side airflow closed completely off.

One thing I did note when trying the side airflow was that it did have a noticeable effect on flavour which became quite muted but the cloud production greatly increased.

Overall, the Anzu performed exceptionally well. There were no leaking issues, flavour was spot on and cloud production was respectable.

What I Liked

Being completely honest, RDA’s are not in my daily vape routine but I have to say that overall I was quite impressed with the UD Anzu.

Building on the deck is very easy thanks to the generous amount of space provided and airflow is more than ample.

The overall finish and quality of the atomizer is of a very good standard for a mass produced device.

The thing that really sold me on the UD Anzu though, was that it is a superb flavour RDA.

What I Didn’t Like

Initially, I wasn’t overly impressed with the aesthetics of the Anzu. Yes, it’s streamlined and feels very sturdy but it’s not the best looking device currently about.

I suppose my one and only real issue with this atomizer is the side airflow. As mentioned earlier, if you intend to only use the side airflow and close the bottom airflow down completely, then the side airflow is not directed at your coils.

This doesn’t appear to affect the performance greatly but it could play havoc with your OCD.

Final Review Verdict


  • Good price point
  • Build quality is very good
  • Velocity style deck and generous space allows for easy building

Smoker for 25 years but now a seasoned vaper of four years. Started my vape journey on Cig-a-likes before moving very swiftly onto CE4's and Ego’s, which were to remain my preferred vaping hardware for a considerable length of time. When the infamous Nautilus clearomizer was released I move completely away from my beloved CE4 and also dumped my Ego for a tube type variable wattage device. Shortly after this I was on to RTA’s, RDA’s, VW mods and rebuilding. Recently I discovered the joys of Squonking and have become completely hooked.
