AsMODus C4 BF RDA Review

First Impressions on AsMODus C4 BF RDA:


It comes in a tube package and inside it we will found all the spare parts and our atomizer.

A nice looking low profile design is the characteristic of this atom. I got the Stainless Steel version but there is also a lot of other colors to match with your mods. It uses ”810” drip tips with o-rings and the acrylic one that comes in the package has a nice aesthetic and fit perfect in the mouth. The deck machining is well made and gives you a lot of space for the cotton. It has a new cyclonic airflow system with 9 holes in each side. The barrel has a lock system that makes it easier to unscrew the atomizer and adjust the airflow. I am a bit worried about the little juice well because it could cause some leaking when you oversquonk it.

How asMODus C4 works:

The deck is really easy to build, so you just have to put the leg of you coils under the Allen keys and then wick a little bit the cotton in a way to receive more flavor. A tip that I can give is to buy or wrap your coils clockwise so that they will point up with the face.


AsMODus C4 BF RDA Pros and Cons:


  • Two drip tips (The acrylic one is really nice.)
  • Nice and smooth airflow
  • Very cool low profile design
  • Elegant and cool aesthetic
  • Build deck
  • Easy to build and wick
  • Locking barrel system
  • Nice flavor
  • BF mode
  • Dripping mode
  • Clean looking design
  • Price


  • Juice well (Not a full Con)
  • Doesn’t fit most of the 810 Drip tips
  • 510 adapter not included

Final Thoughts on asMODus C4 BF RDA:

This RDA surprised me. I used it in combo with the Pumper 18 from asMODus and it worked really good. The flavor that comes out of it is really outstanding and I could say that it is on the same level of the recurve but only with creamy or tobaccos e-liquids, so I wouldn’t recommend you to use it with fruity ones.

The deck is really easy to build and I couldn’t find any con in it. Even if the juice well isn’t that deep, the new cyclonic airflow system with its shapes make it really hard to oversquonk. The airflow is certainly very smooth and it is my kind of airflow and on how it works we can notice a big study behind it.

It comes with a fantastic acrylic drip tip but unfortunately, I wasn’t able to use any of the tips that I had. This I think is because they are moving into this new style with o-rings.

Suggestions to the asMODus Team 

I don’t have a lot of suggestions this time. You’ve created a nice product but it would be nicer if you could give us a 510 adapter and change the 810 drip tip tolerance. It would be nice if I could install in it some 810 tips from Halfmoon for example.

For the rest big congratulations to asMODus team for this beautiful RDA.
