Koiler RDA Review

Koiler RDA Review:

We recently had the honor of reviewing the Koiler RDA. We were impressed with both the quality of the RDA and the company itself, who were incredible people to work with.

The first thing we noticed about the hardware was the level of personalization that can be accomplished with so many different interchangeable pieces. Regardless of what color your mod, you can make this RDA match or compliment your setup. The AFC rings came in red, blue, black, stainless, and polished stainless. In the future, we wouldn't mind seeing copper, Tiffany blue, and white rings as well in order to maximize the potential color combos. The pieces were all high quality metals with high quality finishes.

The Koiler came with 3 drip tips. 1 brushed stainless, 1 black polymer, and 1 white polymer. The stainless does get a bit hot after prolonged use which is, of course, unavoidable with anything metal as it will conduct heat. Both polymers looked great and conducted virtually no heat at all. The mouth feel of the tip was nothing short of amazing. It was large enough to let clouds roll through, but small enough that it felt natural.  We do wish there was a 510 drip tip connector for the RDA for those who prefer to use a standard mouthpiece. The drip tips are equipped with spitback protective mesh, which is something that is seen more and more across the industry, and we couldn't be happier. Koiler is on the leading edge of this new trend which we hope will soon become a standard. All 3 drip tips have a protector that saves you from sizzling juice burning your mouth.

The flavors popped more than other cloud chasing drippers due to the airflow being slightly cut, but it also held its own in blowing thick, dense clouds. As far as the airflow itself is concerned, we had a difficult time finding anything to critique. We did find that the AFC ring had the air holes quite a bit higher than most other RDA's meaning that the coils either need to be elevated in order to receive direct air flow, (leading to long wicks, which may cause issues on a series box which needs a consistent flow of juice or lower Ω builds) or simply accept that the airflow will go over the top. Our coils were well below the airflow, but we still didn't have issues blowing clouds, and the flavor was still better than most cloud chasing RDA's, it simply may be even better if the air blew directly on the coils.

The post holes (2.8mm) were large enough even for more complicated builds. We found this to be one of our favorite features of the RDA. Large holes combined with the four post holes meant that it was capable of handling thick builds with ease. The dual hole center post was solid copper which lead to better conductivity and less volt drop. We do wonder though, with it being copper exposed to wet conditions consistently, how well it will hold against rust. Thus far we have yet to find any issues. A few things that could be improved are that the center post did swivel slightly while tightening, which did add difficulty to securing builds. The screws were deep etched flat heads which did help in tightening, but because the screws were copper, unless you're extremely careful, they're fairly easy to damage or strip, so caution is advised.

Overall this was to date our preferred, and most successful RDA to use on a series box mod, and we highly recommend it. The post holes are large enough to accommodate the high Ω requirements of series builds, the airflow is wide enough to not scorch your throat, the juice wells are deep enough that you have the juice to keep your wick wet, and juice popping is well contained by the spitback protector.

Again, we'd like to thank Koiler for working with us on this review. They sent the RDA setup and care package without any stipulations so that we were able to provide an honest review for all those of you who care enough to read.
