Full Disclosure: Let’s get all the disclosures out of the way. This RDA was sent to me directly from Vandyvape specifically for the purposes of this review. This will not in any way, shape, or form cause me to give this RDA a favorable review or change my opinion in any way. Some Background Info: This mod was created by the Stefan Z and Tony B. Stefan Z is the guy who used to design tanks for Geekvape. He started Vandyvape and des his own thing now. Stefan and vandyvape have just been killing it lately and in my opinion they have yet to release a bad product. Tony B is the host of The Vapor Trail Channel on Youtube. He has over 100k subs there and he always comes across as an honest all around decent guy. He is really into squonking and he designed the Pulse just for that. He wanted to develop a single coil, flavor RDA that could be run on most of the popular squonkers on the market today. So keep that mind while reading this review. First Impression Out Of The Box: Nice looking RDA, I like the size and the fact that this is a one lunger. This Vandyvape RDA comes with 3 drip tips as opposed to the normal 3 from Vandyvape. I love that Vandyvape always gives you multiple drip tips. Deck looks really interesting and unique. Can’t wait to coil and wick this one up. What’s In The box: * Pulse RDA * 16mm wide bore Ultem drip tip * 14mm wide bore delrin drip tip * 510 drip tip adapter * Pre installed squonking pin * Traditional 510 pin * Spare o'rings * Spare deck screws * Coil jig * User manual (very well done) From Top To Bottom: This is a tiny RDA. It’s 22mm and I know Tony wanted to keep it small on purpose in order to accommodate the types of squonkers that are available right now. Both drip tips are nice and comfortable but I do prefer the ultem one. They are both Goon style and they fit nice and snug. The top cap has a conical design to it. It does fit snug on the barrel and it is held in place by two strong o'rings. You get a satisfying click when you put the top cap in place. The airflow is two circles that line up with two circles on the barrel. The airflow is adjusted via the top cap and it slides around and adjusts very easily. When you take the top cap off the barrel has a cutout on top that kind of looks like a stretched out circle. Right above the airflow the top cap is kind of squared off when looking at it from the top view. The airflow itself is a inverted side mounted Kennedy style. That’s the best way I can describe it. You basically have two tubes angled downward from the side that rest really close to your coils. Very unique and well done. Impressive for sure. While this RDA comes preinstalled with a squonking pin you do have the option of running it as a regular non squonking dripper. Vandyvape has included a traditional 510 in order for you to do that. The squonking pin has a 4mm hex key cutout for easy installation and removal. Of course Vandyvape does include a tri tool for this. The Deck: Pull off the barrel off and you are greeted with a gold plated single coil deck. Plenty of peek insulation with some really nice phillips head deck screws. There are two notches on the side of the deck that help you line up your coil so the airflow tubes hit is directly. The notches also serve another purpose, they lock down the barrel so when you pull off the top cap the barrel stays in place. Very simple yet ingenious in its form and function. There are two oval shaped juice wells that you lay your cotton in. They are not that deep but remember this is a squonker so there is no need for a super deep juice well. Because of the inverted Kennedy style side airflow you can over squonk on this thing and it will not leak. Any excess juice will just go back into the squonk bottle. Again, ingenious and simple. Another nice touch is the squonk hole is actually split so the juice is dispersed to each side of the RDA evenly. Building And Wicking: Postless decks can be a real pain to build on. Mainly because you really have to take your time trimming the leads of the coil in order to get the right height. Tony B and Stefan Z handled that problem as well. Simply use the Ultem drip tip included and measure you coil against the part of the drip that goes in your mouth, not the part that fits into the top cap. This will give you approximately 7mm long leads on each side of the coil which is the perfect length for phenomenal flavor on this RDA. Once you loosen the phillips head deck screws it's very easy to place your coil and tighten down the leads. When everything is nice and secure you need to give your coil a little twist with the included coil jig and line up the ends of your coil with the notches that are cut out on the deck. This will place the ends of your coil at the corners of the juice well. Line up the notches with the barrel, slide on the barrel and install the top and you are ready to vape. Just make sure the airflow tubes are lined up so they are hitting the side of the coil. Vandyvape does include a 2.5mm jig so I am assuming that is the size coil they recommend for this RDA. I tried 2mm, 2.5mm, and 3mm coils. I prefer the the 3mm coils for flavor.
