With the Holmes V2, some of them are leak-free, some aren't. The problem is the removable deck. It screws down with very fine threads and does not use any o-rings, but if the threads aren't absolutely perfect, juice will leak down into the airflow section, and from there, dribble out the airflow holes. An easy fix is to just use some plumber's tape (thread seal tape) on the deck threads. That will seal the leak.

Thread seal tape is non-toxic, extremely inert (it does not react with any of the substances in e-liquid, and can withstand temperatures up to 500 F with no damage (but it will still work if it gets a bit hotter than that).
May give that a try. With my Velocity clone (Tobeco) arriving tomorrow, I may not need to worry about fixing the Holmes. I know you say the PTFE tape is okay, but I always get a little leery adding anything extra to the mix.

Chances are you won't have to. There are only a couple of reports of Holmes -- both V1 and V2 -- leaking not from user error (like filling the drip well then tilting the atomizer too far, sending juice pouring down and out through the airholes). But if you draw the short straw and get a leaky one, it is easily fixed with thread seal tape.

Been trying to find a good 2 post RDA as well. So far....

Holmes V2 - fail - leaks
Petri RDA - fail - see here

The Hobo v3 looks promising, will have to look for one in stock somewhere. Someone needs to get this 2 post RDA right!!
The Petri is by far from a fail in my books. I've been using one since I received it about 2 weeks ago. It holds a ton of juice, mine came flawless out of the packaging, and I never worry about it leaking. That, and if I want huge clouds, my dark horse top fits on the deck. I don't see how that's a fail at all.

I acknowledged in my rant that many people haven't had issues with it, but mine was a huge fail out of the box. Almost makes me think I received an past RMA'd piece. Even if that was the case, the negative post will just be a matter of time before it works itself loose. Press fitting it to the deck is just a bad design choice when it could have simply been milled into it and would never pose a problem. Most of the reviews I have seen have stated the post is squared to prevent spinning, that is not the case. Similarly, the weak threading of the positive post is another issue that will brick the atty. Both of these designs could be forgivable in a $30 RDA, but a $100 RDA should be build to last.

For me only time will tell. I'm on my 3rd build on it trying to gauge what kind of coils I prefer in it. No problems as of yet.
On another note: VaporDNA just put up a new 2 post RDA called the Stumpy. It looks like it has a shorter barrel section somewhere in between a derringer and a doge. Yet instead of having 4 post holes like the Petri and Velocity, it has 2 similar to the Hobo v3. Looks to have a pretty deep juice well too.

I do mouth to lung on single builds above 1 ohm at 16-20 watts. I started dripping a month ago with an Achilles clone which has two posts and non adjustable air flow. It will hold 70 drops (3.5 ml) and not leak laying on its side. As long as you don't leave it past 90 there is no leaking of any kind. I also have a tugboat clone and I like it but when I want tank like capacity and no leaking I'm carrying the Achilles.

Two-post fan checking in! Love The Stumpy by the way...

Also, if anyone likes the idea of The Velocity, but not the price or the size of the atty, check out the Stro Mini by Sacred Mods (I haven't used it though, so I can only comment on what I've seen online -- which is still pretty sparse).

Comes in other colors and SS too, this was just the best pic I could find.

Long live the two-post build deck!!!

Great post!

Also, the Manta v2 by JD Tech. It's almost an Aeolus but with a 2PD (two-post deck).

I had gotten a dotmod petri clone and hobo v3 clone both from angel cigs. I loved the idea of two posts but both clones were just terribad manufacturing so it was hard to judge wether it would be worth the authentics lol. All I read on the velocity really makes me want one but it's just so tall and ugly lol.

Stroh mini by sacred mod, I think we will see a lot of this type of design this year....this design with bottom airflow would be the holy grail for me.View attachment 467592


For sure. I think making RDAs easy way, using three-post decks, are not going to cut it when people get accustomed to building on two-post decks. It's like your coils and posts become a plug in a socket. No serious need for finessing a series of 90° bends in your coils -- a quality center-post build is a basic two-post build. Boom!!!!!!

So true, I have the velocity, two actually and they are a delight to build on as well as versatile. I just wish the flavor was better, and I'm also not big on the "feel" of the airflow if that makes any sense. I love bottom airflow for flavor, so I would love to see a dual offset post design with bottom airflow.


Why not the Era/Holmes? Not the purdiest, but it is what you are syaing.
