Background

 

The KAEES Stacked RTA is a collaboration between KAEES and Tony B from The Vapor Trail Channel. It features a unique build deck with a single “stacked” post only requires two screws to secure dual coils, kind of like a clamp/velocity hybrid styled build.

 

User Impressions

 

Build Deck


Kaees Stacked RTA Build Deck

The Kaees Stacked RTA features a fairly run of the mill build deck. Large wicking ports sit on either side of the bottom airflow. The airflow slots are easily wide enough to supply fresh air evenly along the length of the coil. Both airflow slots protrude upwards from the build deck allowing for more direct airflow while also reducing the chance of leakage.

 

Post


Kaees Stacked RTA Post

The Stacked RTA gets it’s name from its single post building design. The post features two sprung plates that sandwich a Zirconium insulator.

 

Airflow


Air is bottom-fed through two adjustable cyclops styled slots and up through the deck and aimed directly at where your coils will sit. When wide open, it’s definitely one of the airier RTAs I’ve used, but it produces decent flavor through the airflow range.

The airflow adjustment ring can be quite tight at times but is easily removed for cleaning/lubricating with e-liquid.

 

Ease of Building

The single post design is quite a novel idea. Before receiving the RTA my expectation was that the single post design would make building quite a lot harder. I was picturing juggling each side while trying to get even pressure and also holding each coil in position would somehow just not be possible with only two hands.

 

Filling


kaees RTA Filling Ports

Filling is pretty standard, screw off the top cap and you have two very large ports for filling. What I did find though was despite having air escape holes under the top cap, it still dumps out half of the tank when screwing the top back on. To avoid this, I close off the airflow entirely before unscrewing the top cap and then after filling I give the cap a quarter turn and flip the whole thing upside down while tightening it fully. I haven’t had any leaking issues when topping up like this (nor has the tank leaked in normal use).

 

Build Quality


Build quality on mine is great! All of the threading is smooth, the black paint/coating is even inside and out, and the O rings are all nice and tight. The only issue is that airflow ring being such a snug fit sometimes, but as I mentioned, it’s easily fixed.

 

Final Thoughts


This is a solid tank which I happily used all day. The flavor is obviously much better than your average sub-ohm tank and I’d say it’s above average for RTAs. I found building the Stacked surprisingly easy. With one little trick in filling it, I’ve had an almost 100% leak-free experience. Overall it’s definitely an RTA I would recommend.

Pros

  • Great build quality
  • Easy to build
  • Superb wicking, never had a dry hit
  • Good amount of airflow
  • Above average flavor
  • Holds up to 5ml

Cons

  • Airflow control ring can be very tight if not properly lubricated
  • Can leak like hell if not filled correctly
