RSST vs. AGA-T2: Battle of the Entry-Level Genesis Atomizers


RSST vs. AGA-T2: Battle of the Entry-Level Genesis Atomizers

Some rivalries capture our imaginations to transcend and become iconic battles: TIE Fighter vs. X-Wing, iPhone vs. Galaxy, or Mustang vs. Camaro. In a short time “RSST vs. AGA-T2” has become the genesis-style atomizer equivalent in the vaping world. Each of these entry-level genesis-style atomizers has positives and negatives, as well as their own supporters and detractors. But if you’re looking to jump into the gennie world, which is the right for you? Let’s size up this battle…

SmokTech RSST

The RSST began life as a “tribute” to the AC9, a highly respected, but highly expensive genesis-style atty. It’s not a perfect “clone,” but the similarities are too glaring not to notice.

The RSST’s main advantages are ease of build and insulation. Some gennies are prone to shorting out when an insufficiently carbonized mesh wick contacts the wick hole and/or conductive bottom of the tank. The RSST gets around this with an insulated wick hole and a plastic-bottomed tank.

The RSST also features a spring-loaded coil end trap. Rather than threading a screw down to secure the coil end, the builder simply squeezes it between the post head and a spring-tensioned washer. This is intended to be dead simple, but sometimes becomes a highly frustrating experience.

But there are some drawbacks to the RSST. The top post insulator tends to leak, which often results in a build deck full of juice (replacing that piece with an AGA insulator usually yields very good results).

Also, the positive post runs from the top of the atty, through the plastic tank, and connects with the mod. It is held in place by a small plastic “nut.” It’s necessary to remove this piece to disassemble to RSST for cleaning. Unfortunately, this small piece is very easy to lose, and there is no replacement offered for sale. When that bolt falls into the kitchen sink (as I can attest from personal experience), your RSST is useless.

For all intents and purposes, the RSST is a single-wick only device. I have seen some dual-wick builds using the fill hole, but it is a poor solution at best. In addition, the top cap tends to fall off if you accidentally look at it wrong, and I have found the RSST’s 510 connector threads to be made from poor materials and become wobbly after extended use.

Youde AGA-T2

Youde makes solid entry-level devices. The AGA series began with the AGA-T/T+, and was followed up with the T2 revision. The line has since grown to include the TD and T3, but it is the T2 that became Youde’s genesis calling card.

The AGA-T2 is an affordable, flexible stainless steel RBA that’s about as easy to build as it gets. It is designed primarily as a single-coil device, but it’s fairly easy to remove the extra negative post on the deck to reveal a second wick hole.

In addition, the AGA has a pyrex tank. Glass tanks are subject to breakage when dropped, but they are also not going to crack when vaping a cinnamon or citrus juice. And they clean up real nice.

The AGA-T2 has a sturdy cap with excellent o-rings, and I feel comfortable pocketing it when going out. It does not have a fill hole cap, but I have never found leaking to be a problem. Vacuum keeps the juice in place, unless one is trying to vape while doing crossfit.


OK, I’ll Ask Again: Which Gennie is Right For Me?

I consistently see recommendations for the RSST over the AGA-T as an entry-level gennie. I think it’s one of those things that just became accepted conventional wisdom, even though it’s not necessarily wise.

The bottom line is, both are bargains and strong performers in their price range. However, the AGA-T2 offers more flexibility and better construction quality. Unless a pyrex tank is a deal-breaker, I recommend the AGA-T2. It is also generally cheaper by about five bucks. Treat yourself to a beer with your savings, and vape on.

  1. This is a very good debate especially for all the noobs to rebuildables. I have both and I have to say I like the rsst more. Sure it has a few little kinks, but what doesnt. The rsst is one good cheap way to learn how to build your own. Oh ya and lets not forget the clouds of vape you that the rsst chucks out. Its a great way to learn how to fix all the little aspects of rebuilds. Not that there is alot but 3 I can think of. I have several other attys. Closing in on spending 2 thousand on tanks. Dont tell my wife…… and I still use the hell out of my rsst’s. I have 3..

    • I’ve been using the AGA T2 for over two weeks and find it a wonderful entry level Gennie.
      the extra hole is outstanding for double coil builds which normally gets me around .4 ohms.
      And the clouds are amazing, My ideal set up is 1.5 or so, On a safety tip; I never go below .3ohms of resistance, it’s like warning will Roberson danger danger.
