528 Customs setting out to improve on the original Goon was no easy task. In fact, most probably would’ve left it just the way it was. Regardless, 528 managed to bring something even better than the original to the marketplace.

Let’s get down to the nitty gritty!


  • Built very well
  • O-ring tolerances are perfect
  • 810 drip tip
  • Super easy airflow adjustment
  • Huge airflow slots
  • Stainless deck makes for great connectivity
  • Post holes are huge!
  • Can fit large diameter, and complex coilart; pretty much anything you throw at it
  • Bridge clamp posts are an absolute breeze to build on
  • Squonk ready (comes with pin)
  • Copper 510 pin
  • Professional logo. I mean it really looks good!


  • 50% or more airflow restriction is not possible
  • It’s a bit on the heavy side, which may turn some away
  • The clamps can get a bit ‘sticky’ at times


Full disclosure, going in to this review I had no prior experience with the OG Goon. So you’ll have to take my positives and negatives for what they’re worth. With that being said, I truly believe that the V1.5 is an excellent RDA. It has all the features one would expect from a ‘higher’ end RDA, and not much else. The design feels very utilitarian, while still managing to keep that sleek form factor. I used the heck out of this RDA, searching for any flaws in design, or something that just didn’t seem right. Fortunately (or unfortunately, depending on how you look at it) I did not find much.

One of the biggest problems with the Goon V1.5 has got to be the wonky airflow.


At first glance, it doesn’t seem like there’s an issue; it’s only until you start using it, that you encounter the problem. If you like a nice restricted draw, you’re going to have a difficult time with this RDA. It’s too bad, especially considering how smooth the airflow is — but any adjustment beyond a 50% decrease, and the slot/s start opening up from the other side, killing any chance of dialing everything in. Thankfully, the Goon V1.5 has a nice deep swooshy draw, so I was able to enjoy my vape with everything wide open.

I’m sure there are companies out there banging out new top caps for the Goon V1.5, and that should eliminate that issue all together. But for now, vapers looking to purchase one are going to have to live with the lack of adjustment.


Besides the airflow, 528 Custom Vapes did an amazing job. The topper is a real pleasure to build on and vape. Would I purchase another? probably not. Would I purchase an updated version of the RDA? Absolutely!
